Normally take destroyer always have some weakness such as no turrent low mobility or low health for other player to counter play.Jackson once have low health but now it have health buff cause it to lose all weakness in this unit.There is no counter play such as flanking or close distance to exploit it low health.
Don't come up and say "Jackson is tank destroyer it suppose to counter tank"
All of tank destroyer have some weakness to exploit.
Su 85 no turret allow flanking.
m10 have short range and limit turret rotation allow it to be hit from out range or flanking.
puma have low health allows enemy to close distance and exploit this weakness.
But jackson have non of that.
Panzer 4 stand no chance Vs jackson. Low accuracy on the move cause it to miss almost every-time.Jackson have great range and accrucy.It can keep snipe panzer 4 from range with out problem.But the reason that i consider jackson OP is it does not reward any counter play such as flanking or closing distance to the enemy that manage to out play it.
So i suggest to neft jackson health or range to allown it to have some weakness or have less impact on the game.
right now with the current range it can create AT cover bubble that cover one quarter of the map plus great mobility cause it to moving around very quickly make almost shutdown enemy medium tank play.
