so...... OST doesn't have 5 man squads by default, everything of OST is a one trick pony too. So whats your point.
Compared to rifles the compensate that with higher dmg from kar98 and better accuracy standing still vs Rifles and with G43s better moving accuracy and also higher damage but lower overall accuracy. You win some, you lose some. Also cheaper so it does fit in nicely overall with OST.
I'd say Jackson should penetrate 9/10 hits on max range to most mediums. Less than that it becomes slightly unreliable since it can't bounce anything. It's still a greater matter of map design and game mode than any "balance" problem.
OST Panzer IV can take on Jackson if it gets close to it, easily since the large target size won't matter close range to P4s 0.5 moving accuracy.. If the Jackson is supported by at least one unit to utilize max range and get the first shot in, then no. Even with the windup/down, Jackson is the best AT tank currently in the game, probably followed by Stug or JP4.
Vetted Firefly is cancerous when supported. There is no doubt that Jackson is on top of the food chain when it comes to pure AT power, denied only by heavy tank destroyers and paks. Does that warrant a nerf? Not really. Something else would take the spotlight then as the best AT gun and there would be debates about that being OP.
This whole thread is pointless tbh. Jackson is only good vs AT and P4s is a generalist tank and both can kill each other and excel in different parts of the game, with different timings. Heck, 1v1, AEC can take on KT by just running around it. Doesn't mean AEC is OP nor KT is UP.
