At the moment they just repair faster, yes...a reasonably useful ability for a tank heavy doctrine. Its one of those units which lost its original purpose(which was OP) and is now in...somewhat on a limbo where we're working out how to improve it or replace it.
The mechanics for the tank heavy doctrine.hmm, i'd give them overrepair and move them to they're the first doctrine unit as opposed to the lend-lease sherman. maybe make them tougher too.
I like the mechanics. They're expensive but with veterency, I like to pull my tanks when they receive a lot of damage. they're the only unit that repairs reasonably fast. On the IL2 strike, I think its awsome but with the munition upkeep thing, I find it really difficult to use, even when its unlocked.
OSTHEER IS DONE WHEN IT'S DONE!
