This vomparison is very misleading. Raw penetration values mean nothing. Also accuracy values (plus ideally scatter) is missing. I don't have their current stats at hand, but SU76 got a rework a year ago or so where its accuracy was nerfed iirc. I don't know about how it compares to the Stug at the moment.
Additionally, the increased health and the 40 difference in damage are a huge deal. It's the difference why StuG is a very effective anti medium vehicle while SOV players rarely go for an SU76 to counter mediums. SOV has more cost effevtive AT units, yes, but the SU76 is quite unreliable especially against OKW P4s and the low damage make it very hard to actually finish it off.
I don't think OPs suggestions would fix SOV T3, but I also doubt that it would make the SU76 broken.
Not sure how I missed accuracy, since it was in the video and my notes. Anyway:
SU-76 Acc: 0.05/0.04/0.0375 (at 0m/30m/60 range)
StuGG Acc: 0.06/0.05/0.04 (at 0/25/50 range)
Scatter angle for both is 5. Distance offsets/ratios are a bit different, but to be honest, I don't know how those impact gameplay.
As for the rest, I know the SU76 isn't effective against OKW's P4; I specifically made the comparison with OST for this reason. OKW also has the JP4, which at 60 range, can return fire - its the same reason why OKW is much less vulnerable to "60 range TDs" in team games (M36, SU85, etc.). As for OST, the Stug's armor is low enough that the SU76 has a 100% chance to pen at max range, but its speed and range is low enough that it can't return fire. Meanwhile OST has no 60-range TDs, meaning they can't actually return fire.
Yes a slight mobility increase to the worst and most immobile TD in the game, which noone builds, will make one of the best TDs in the game into an absolute joke. Never mind the fact you called the StuGG underwhelming.
You’re talking about units you don’t understand.
This is objectively false. The Su76 is actually one of the fastest and most mobile
TDs in the game, and the fastest and most mobile
case-mate TD in the game.
Current "live-game" stats
Su76: 6.3 speed, 2.3 acceleration, 30 rotation.
OKW's JP4: 5.5 speed, 1.9 acceleration, 20 rotation.
OST's Stug: 6 speed, 2.1 acceleration, 28 rotation.
SU-85: 5.7 speed, 2.1 acceleration, 22 rotation.
Taking the fastest, most mobile, case-mate TD in the game, making it even faster
, while keeping its 60 range will inherently make a slower, 50-range, more expensive TD a joke - especially when it has a 100% chance to pen.
