You say everything's fine. You're like an old broken record, it saddens me.
It comes too early to have unavoidable-squad-wipe ability. Effectively if you see it, you have to retreat your inf. Not just walk back to cover but retreat to base.
And what saddens me is that 100% of units are always imbalanced in some players heads, but it doesn't stop them from complaining about everything.
Guess what? In CoH1 it was instant shot that could wipe whole blob and it was fine and stuart could fight light armor as well.
Its fine as well here.
You'll squad wipe only if squad clumps up.
Greyhound is squishy, arrives when you have plethora of counters, looses to scout cars(pair of 222s will obliterate it and its not like pair of 222s is a bad idea against USF to begin with), looses to puma, even Luchs makes a short work of it.
Its expensive at 280mp 40fu, which means there will not be any AA halftrucks, its ability isn't instant, so retreating squads that weren't cut off are safe as well as garrisons duu to spread.
Its 100% AI light vehicle in a doctrine that is overall quite poor. Its the only cost effective thing in the doctrine.
I happen to have that doctrine(my only doctrine that dropped for me since WFA release) and while it can squad wipe, its not 100% chance and Wehr have all the means to counter it, just as OKW.
