This tank is an absolute monster! It's everything you could wish for in a heavy (reliable armor and a great gun). I had enough free xp to unlock the turret, so I did that and used the best KT's gun. It took me (only) 60 battles to unlock the 12,8cm gun. So far I've had 75 battles with a 65% WR, by far the best results than in any tank I ever had (yes, I realize it's a small sample size). I have yet to unlock the suspension and the engine.
My current equipment is as following: rammer, vstab, Enhanced Belleville Washers.
Crew skills: sixth/preventive/safe for first, BIA for second, repairs at 40-ish percent as third.
My question is should I unlock the engine or the suspension first? If I go for the suspension first I could remove the washers and put something more useful in that eqipment slot (vents or gld, haven't decided yet (leaning towards vents because I didn't find the aim time to be that big of a problem)). On the other hand, there are games where I really miss the engine power, especially if I need to go up a hill or half way across the map.
