Please help with my hanger

Switch the Griffin Molots/Spirals to Taran/Magnums. Switch the Vityaz out for a Boa Thunder/Orkan. Switch the Molots on the Leo to CRV Pins. Keep the Gareth for now but later on switch it out for a Griffin with Aphid/Pinatas or Orkan/Pinatas.

spirals don't do enough damage, stop using those. in fact, for the most part, try to use as much WSP & Gold weapons as possible.

also, the long-range game is something you won't want to use until later in the game, so i recommend you trade out the leo set up for thunder + aphids.

also realize, that no matter what you use, there is going to be a constant up-then-down-then-repeat in your matches, so there really isn't a 'bad' hangar. there are definitely some that are more effective, but you will eventually figure out whats good because its whats killing you the most. like once i got to 4/8 mediums, i found myself up against heavies, so i had to adapt by getting heavies. eventually i got 8/8 heavies & +300 avg dmg, then i found that i usually die by tridents & zeus, so now i use those.

With that lineup, here's what I'd do:

Swap the Vityaz and Leo in their roles. You're right, Vitz is fairly quick. Slap the Trident and two Pins on there, and that's your mobile midrange bot. It'll go places faster than Leo, and midrange is ALL about lining up a good shot. And getting the heck out of Dodge if your position is threatened.

All those Leo hit points are being wasted. Leo isn't really the best at anything, except doing everything tolerably well. However Leo's best setup is still the Thunder Pinata combo; at point-blank range it has more burst firepower than a Lancelot...at least until the Pinatas are empty. Even at base level, three Pinatas plus a Thunder is a pretty hefty payload. And Leo is survivable enough to walk up to an enemy and unload in their face.

Keep Gareth as-is. Like mine so much (L8/8/8 plasma setup), I just bought a second. Which is armed with plasma and will be leveled to match my other Gareth. Gareth is Da Bomb.

As far as #4, the Thunder/Taran Boa is good, as others have suggested. Or you could throw the Zeus and three Pins on that spare Leo and run two midrange...not usually recommended to have more than one, but it can be done.

Looks good, keen to test it out a bit later tonight.

Yeah that is a very good start... You can switch up the mid range weapons and try them each on each bot to see what you like better, then I do suggest knocking it down to one, but then again, you will be matched according to damage dealt, so, you may be better off right now, with what you have.

Honestly, my overall advice, fwiw, is to take what has been said here and run with it. You are learning about how weapons combined with the right counterparts perform, and you are learning the bots that work well in the meta. Don't be afraid to try different setups within the guidelines given to you.

The Trident Pin combo is a good example... 3 main Ag bots that people use for that setup are:
1) Leo Trident + 3 Pins

2)Vitz Trident + 2 Pins

3)Golem Trident + Tulumbus + Pin

Out of those, the Golem is my favorite, then the Leo, then the Vitz... but that is what is so nice about this game, what I like may not be what you do, and you can try anything you want

I agree with Ron, get the Trident leveled ASAP. You CANNOT judge its effectiveness at that level.

Also, that Zeus can fill in the same spot as the Trident on each of those bots.

So, I think you have a very good start, now take it a step further as you learn how these setups work or don't work for you, and make them YOURS.

Good Luck!

I would personally run the gareth, leo, griffin, and boa.

Gareth always, it's a great beacon capper with that shield. Use it to skirt around the reds and cause some of their units to divert from the front lines.
Boa has high durability, use it with a thunder and taran.
Leo has high durability, use it with a thunder combined with pins, pinatas, or magnums. Possibly use the trident and pins on it for a nice mid range effect and the thunder on the boa.
Griffin with tarans/aphids or magnums. Orkan/pinatas. Tulumbas/pins

These are the main types of combos you should be going for right now. However, this is all up to you and your play style. That is just my personal preference. I always ran my Leo with thunder/magnums but you'll see more outfitted with pinatas for knife fighting I think. I just preferred the continuous fire from magnums.

He only has 225 victories and no 5th slot. 
He can't afford an 2 orkans much less 1. 

Gotta think from a new player's perspective.
