Which WSP Bot For 5th Slot?

Rhino is a very hit and miss bot, I love mine but it's shortcomings are huge.
I think a Carnage has enough flex to be useful in most people's hangars.

I like the Rhino, which can take your PDB Griffin's plasma loadout (and you can instantly make a second RDB loadout at level 5 for the price of a little more Ag). Available weapons might be the most useful factor in deciding which bot to get next. Eventually you'll probably have at least one Rhino, Carnage, and Fujin, if only to experience how they operate - because eventually WSP will come in faster than you need them.  

Be aware, however, that not everyone likes Rhinos and they have a steep learning curve. They won't move until leveled up to 7 or so, at which point they (a) barely move with the shield down and (b) only move forward with the shield up. With all of that said, I prefer plasmas on my Rhino compared to on my Griffins (3 of 'em) and I enjoy the Rhino's straight-line speed to relocate across the map. I think it's faster than Carnage in terms of relocating any significant distance, although Carnage on rush is obviously both quick and nimble (something Rhino can never claim!).

Carnage. It can be used right off the bat with the default thunders. If you are not sure try the test server and give it a whirl and test drive the rhino.

My two-penneth on WSP 'bots:

I have a Fujin, a Carnage, a Stalker and 2 x Rhinos.

At the moment only the Carnage gets a regular run-out: about 60:40 Thunders:Tridents (2 of each, I don't mix ranges). I have a couple of Zeus but have not yet levelled them up. The 'bot is fragile but carries a heavy punch, just don't get caught in the open. It plays nothing like a Boa.

Before the Britbots I ran the Rhinos frequently - they are probably the most difficult 'bot to pilot well, and I still need a lot more practice - with the preponderance of mid-range splash weapons they can be very vulnerable.

I bought the Stalker to better understand its strengths and weaknesses so I could counter it better. Only used very occasionally for variety - not really my play-style.

I only bought a Fujin to try it out for variety.

I currently have no desire to get a Raijin.

With reference to your current hangar:
I think plasma Griffins are very vulnerable to the shield 'bots - I prefer DB or RDB. Once I have got round to levelling the weapons more I may even try out a hydra/spiral load-out for variety. I have seen plasma Griffins used to great effect, just seldom by me.

Now that there is little penalty for doing so I would recommend prioritising getting 'bots to level 9 - max speed makes a BIG difference to fun and effectiveness.

Have you considered trying a Cossack? Great beacon runner with a Taran - unfortunately far too fragile for later high-level play.

I have tried the Hydra Spiral Griff

annoying as hell for the reds... not that much damage unfortunately for 2 meds& 2 lights but 600m range
Found it best to bring out late on when the field was thinning and maybe people were carrying damage ... useful for picking off that pesky red beacon runner trying to flip a beacon back ...definitely not a heavy hitter
my 2p

Rhino. Carnage is only good if you have Zeus or Tridents which I assume you do not have. Thunder Carnage will not last more than 1 minute on the field.

from just my experience and I am no expert the Carnage is versatile, can carry thunders, tridents, and zeus. I have all three and swap out depending on my mood. I always lean towards the Zues but if you cant swing the gold then Tridents are the way to go!

Was suprised how many veterans run Thunder Carnage in TT. Been looking at the hangars in the Legends-League today and found that 12/12 Thunder Carnage is not uncommon beside the expected Rhino, Fury, Griff and Lance.

So the Carnage will serve you well for a very long time. When I got mine I bought a second one shortly after, Zeus, Trident and Thunder setups are a lot of fun.

Thanks a bunch guys! So much useful info here. Carnage it will be. Seems very versatile but it will be tricky to pilot. His shield is easy to counter/play around most of the time. In many matches i'm on 1v1 with my leo and a thunder carnage and can pop it with 5 thunder hits from 500m to 300m and then release my pinatas. Probably not good piloting by the reds perhaps? Although, If he can to get to 200m from me with the shield up its usually game over for me.

Yes, poor man's plasma here. Griffins pack a punch but are fragile for that job. I'll confess I really lack on the beacon capping area. 0 to 3 MAX per match. I'll use my gepard for now but i'll definitely try a cosack. It will be fun.
And also Bots get max speed at lvl 9??? Didn't know that...

Hahaha! Exactly this! Raijins are target practice when there's nobody else around to shoot at.
I've also found the aphid stalkers to be the most dangerous. i've regretted every time going solo against them.

I was in a similar situation too in a match. My pinata leo and a plasma fujin. We killed 5-6 bots once we parked before we went down

Most if not all have allready written here but one thing what came to my mind for looking your carage is:

All your bots are kind of slow. (1 jump per 30sec do not change it)
Try out medium silver bots. True, you will NOT use them high level but now your bots are lvl 6 so most of them should be medium/light.
Around lvl 8-9 (all bots) most start to be heavy or "special" bots (carnage, fujin, galahad)

You are in great spot to try out different things (without paying too much time/silver for it) so try out how fast and agile while still having enough hitpoints to take damage lvl 7 Boa is, (one of the great medium silver bots to actually get over lvl 6). I would take Boa against Leo in knife fight pretty much every time.

While you keep your heavy bots lvl 6 why not give a try for lvl 7 Vityaz and Golem allso? (I have them in my storage not in use anymore but still...) They help you to move faster for battle and get some gold while you wait for enough gold to get your Galahad (you DO need atleast one fast bot for capping and Galahad is great for fighting allso but more for defensive fights and capping)

When you get 5 slot give a try for Natasha allso, not so terrible as most people tell you, just use her for long range fighter and move a bit (yes, even cap). BTW you really need medium range bot around lvl 7+ not before. That is time when carnage become something to consider with 2x Trident, you can first use these tridents for Natasha while your Carnage get leveled up. Reason for lvl 7+ is because tridents do not do enough damage and Carnage is way too easy to kill let's say lvl 5 all)
