OSTHEER IS DONE WHEN IT'S DONE!
I agree. I don't like breakthrough at all really.
Breakthrough and Propaganda are sort of weak at the moment being as I see... "unfinished" with both having problems Propaganda with GOW and the first selection defences (Trenches and MG) and Breakthrough with Mechanics and as per this topic the ISU-152. That said the only problems I've see or heard about with Urban is the KV-2 which is apparently sort of without use late game apart from being a great base breaker (I wouldn't know I hardly use it).
To be honest the only problem i have with it is its beasthunter ability as it seemingly does nothing.
A good summery of the problems with all the Russians doctries.
Propaganda's issue is with the 1st ability on either side which should be combined into one ability on the right and a new zeal type power ability on the left.
I am think that tank must be unique unit in game, like King.Because ISU like King: same armor and HP and great firepower. But if King destroyed we will lost him forever, and if we lost ISU - we can easy call a new one.I think it's not balanced.
