And last but not least, but yet again-222 IS overpowered when you compare its cost to what it does.
I can't help but laugh a bit. Do you even need an AT gun to counter a 222? Put a squad on cover and the 222 will just run around and make noise and do almost nothing. Only the vanilla 251 is more worthless vs infantry. So 2-3 222's can counter an unsupported T70 or an AEC, big whoop, manpower is the issue here. The T70 can run around and deny entire sides of the map or else face having your squads wiped on retreat. When was the last time anyone had to retreat a full squad from a 222? Meanwhile you've invested how much manpower in 222's vs a single T70? A T70 that can actually drain your MP while the 222's drain nothing but the will to live from your pios as you have to repair them every 60 seconds from small arms. Then a single AT gun arrives, one which you can circle if you so desire but dont plan on decrewing it anytime soon. Calling the 222 OP is just lol. When it arrives it has a viable lifespan of maybe 2 minutes before its obsoleted and you surely can't say the same for the AEC or T70 or Stuart. The only time its more than meh is for spotting scope maphax which will likely be fixed someday pending lelic.
