Campaign mission for obj.260 impossible after mm update

Shooter8995, on 01 June 2017 - 12:33 PM, said: HT-6: A Heavy Target for obj.260 as u see on picture is impossible after matchmaking update...Why?...Because no matter what tier u pick from VI-VIII only tanks u get from higher tier is one heavy,one medium and tank destroyer...So basically that mission is impossible for new people.... I would suggest to change it for primary conditions to -Destroy at least 4 enemy heavy tanks that are the same tier or higher...that way is possible and it is hard enough like that.... So please consider to help me suggest this mission to change it ^^
