wait wait wait.... just increase the cooldown time, its only a little longer then an Su 76 call in, that would bring better balance as to stop any spam. the cp it takes to get it is already enough. as for manpower if its a regular t34 it can be 600. if its an upgunned 85 then 650. then you might asked, well im not gonna get an upgrade to save 50 manpower. well, then what are you gonna pierce panther/tiger armour with???
