I prefer to play mobile tanks, but I can do well with slow tanks too. The slow tanks must have decent enough armour (eg Tiger P, Churchills) to make up for the slow speed. Crew is about 70% into their first skills, tank is maxed out for the time being. I am starting to get to grips with this tank, it drives like a halfway between Tiger and Tiger P: armour just good enough for the occasional bounce at ~300m, but don't rely on it for brawling range. Fighting tier 9 and 10 opponents are pretty fun, the mere presence of a KT will cause them to think twice about being aggressive.
