The 222 still has it's weaknesses. It's not like it's invincible at the time it's deployed. It still takes damage from small arms, and just about any AT weapon would easily drive it away. The HP buff was necessary, but an increase in cost would make it undesirable again due to it delaying further tech. It's price right now is as perfect as it can get, and it's really difficult to change it without making extremely OP or extremely UP.
It sounds like it could be a really nice feature, but I'd rather have it just re-crew the weapon with just 2 models instead of being fully re-crewed (because for 100 manpower though). Then after re-crewed, they could simply reinforce the other models. It would also be nice for the halftrack to have an upgrade which would allow it to transport small weapon teams such as the mg-42 and mortar. While we're still on the topic, maybe even figure out how to tow larger weapon teams (ex. pak-40).
I don't wanna seem mean or unfriendly, but to be honest, ur playercard shows u have played zero games at least in automatch during the last month! and if by response time you mean the aim time, it actually has very short aim time which is one of the advantages of it.
Maybe he's just been playing that "balance mod" for the past month?
I mean the same goes for all team weapons. Maybe increasing the crew to 5 wouldn't be a bad idea but the camo does provide a lot of utility. The best comparison would be to look at the maxim and .50 cal.
It seems to happen to the Raketen much more than other AT guns due to the squad formation. So, either Relic fixes the squad formation for 4-man squads, or they add another model like you suggest.
