Why can't I shoot Orkans right?

I keep hearing that you have to lead the targets a little bit but I find that to be spotty at best. I just keep shooting and live with it. I definitely seems to be a bug that they're in no hurry to fix.
I run three boas with tarans so I feel your pain.

I read you just fine the first time. Conventional wisdom is to lead your targets a little. At max range this can be spotty at best because flight times are so long. Occasionally you get an entire salvo that seems to miss at long ranges for no apparent reason though.
This could be due in part to a faster opponent backpedaling which when combined with a slow rocket speed means they've moved out of the splash radius by the time it reaches them. Shooting from high angles above they can even walk right past (think from a bridge on yamantau). It's easier to correct for when it's left to right movement because you can lead. Back and forth your best bet is to get closer to minimize travel times for the rockets.

Also, it is not a bad idea to practice with the Pinatas... same rockets and less forgiving if you miss since Orks can reload while firing and allow you to continuously damage/annoy your target... so I find it encourages me to hone my craft. IF you can get good with say, a Patton Pinata, where missing usually means you are dead due to the lack of any shield and low HP (relatively) but hitting with all 4 will cripple the big guys and destroy the little ones (usually), then by the time you are running an advanced bot/load-out with Orks, you should be more than capable with them.

I practiced with level 1 or 2 bots (Gep, Patton, Destrier) and some brand new lvl 5 pinatas... 2 or 3 bots outfitted with them, and I used them constantly for a few games. Dropping that low in tiers usually puts you against fast bots as most people run either beginner setups or Geps at that level. VERY hard to hit. So, if you are OK with losing at first (dropping that win % and damage earned average), until you get the skills up, it can be a good way to jump feet first into the fray and figure them out. Stats can be recovered since it is just an average of past 50 battles... and is a useful weapon to be good with.

IMHO

Just FYI, I played a few games just now, and the only robot I have with Orks atm is the Boa with a thunder. I tried to take note of when I used the orks the most this time to better answer your post, and tbh, almost all of the shots were ambushing (Like the post above said, waiting around the corner is one example, took out a lot that way) and holding on to them until the very last second, absorbing their opening salvos sometimes in order to get close enough to "see the white of their eyes," as that old WW1 ace would say. Not much leading going into it, very few times did I even pull the trigger over 200 meters. Since I paired the Ork with a Thunder, it works outstandingly up close in conjunction. Little to no skill needed if they don't move... and if they do the Boa makes it pretty easy to keep sidestepping and/or circling them (say, if it is a shield bot like a Rhino or Rajiin.) So, it may not be that people who use them well are much better than you at it, just that they wait until there can't be much of a miss... at least, if my experience is any guide. It is very much a "bait and wait... devastate" type weapon.

So, my question to you is, are you trying to use them at their max range on moving targets? If so, maybe just wait till you get a little closer and for them to focus on someone else, then just give them the reward for their good behavior.

P.S. I am not saying you cannot hit them at 300 - 200 meters effectively, many do, and I do remember a few shots that I hit as soon as the range got under 300m... but if they are moving perpendicular to you and you have to lead at that range, it is almost a guarantee that some of the salvo will miss, even if you are perfect with your placement. Especially a fast bot. They will still feel it though, so if not a 1 v 1 battle, it may be worth emptying your magazine just to soften or distract the target. All depends on the situation.

Thing is, Tricky48, getting into that ambush position and getting to under 200m is a skill in itself. Sure it's not much skill once you get into shooting position, but getting there isn't always easy.

I usually run a thunder taran boa but I was trying out the new cossack speed.

Fair enough, then the only issue I have had at when they are moving straight at me is when they are in a bot that can outrun the rockets at the 200 - 300 m range.  Galahads, Gareths, (With shields down), fast light bots, Bots with Rush or Assault abilities, etc.  IF they see it coming they can backpedal and avoid most if not all of the salvo, as was stated above... but otherwise I haven't noticed anything amiss... pun intended ;p

I do not think that running forward will cause the same miss, by those backpeddalers, as I haven't looked for that scenario.  I would assume running into the fray will not save them the way running backwards would, but that's just a guess.

And roger that on the quote... I swore it was the Red Baron... lol

I think that it is straight out of the launcher... 

at 1st i also have some difficulty on using orkans, i just watch youtube and see how other people use them, then i start using orkan with cossack. if you can successfully run orkan with cossack then you can use them with other bot
