Did you sell everything out of your depot as well?
Yes I did, I spent a lot of my cash on the M7 Priest, I enjoy switching out between matches of if I get killed early, plus I just love being the only spg to be on the front lines, Get some pretty good action in that and comes in handy when we need to push. Also like to go tank destroyer with it sometimes hehe my aim is amazing
With the germans, most of the engines you get you can use on 40% of the other tanks. I always get the bigger engines on the tier 6+ tanks etc. 88 L/71 is one of the best guns in the game.
upgrade all the engines you can on the e-100 line, Tiger I and II, and e-75 really shine once you mount the final engines (bonus if you're going down the e-50 line later on is having that 1200 HP baby already researched, just got my 50 yesterday and wow what a beast!)
Then i'll go ahead and buy it then, speed could save my life, it could have numerous times before..
Edit: here's a question, with IS-3 and KV-5's I find I can't do anything with AP rounds, HE is the only round that does much if any damage. Which shell is more vital to have in a high tier battle? HE or AP?
