fire cone increase would help tremendously. would it be possible to get some background on how you guys decided to balance it?
Right now you have a gun that moves slow and turns slow, and with it's tiny firing arc that all hurts it. You have 3 very big things working against this gun and the only thing you have working FOR it is high penetration and more HP, which as far as ATGs go does not really matter, if it's going to get over run, it's done. If it got a firing arc of 85 it would alleviate these problems, I even think it would be fair to fire slightly slower if the firing arc was increased.
The 17pnder is not supposed to replace the 6pnder, it's supposed to act as a heavy AT role. I doubt you would care it's slow turn and narrowish fire cone when 2 will destroy a KT in a decent amount of time.
It's penetration is king for price and it also doesnt suffer from RoF reductions like the Pak40 does compared to the Pak36, ergo, the 17pnder fires just as fast as a 57mm.
The long range accuracy is also much better than the 57mm, at .85 for long range, if you properly spot for it, you shut down any armor. This is the tradeoff for the smaller firing cone.
Also, pen and HP mean absolutely everything for ATGs. Damage doesnt mean crap if you cant penetrate and the 17pnder will penetrate any non doctrinal tank over 85-90% of the time on average and every super heavy with ADPS rounds. This also effects how well it will do in an ATG fight.
The 17pnder was not overnerfed, it was brought into line. Before, it had the stats it has in the emplacement which were super powerful for being immobile. It's got a role, it kills heavy tanks better than the 6pnder, use it for that. Saying it is "outpreformed" by the 6pounder is a matter of perspective if anything else.
