Kenne, just because it doesn't fit into your type of game play, doesn't mean that there isn't a place for it here in AH. The 75mm Sherman is going to be a great for the gv'ers in the game. It'll make taking bases fast and less vulnerable than taking a wirble into a town.
Personally, I don't care for the Spit 1 either. I prefer the Hurri 1.

And if you look at the stats on Hurri 1 and Spit 1 pilots in the MA, I think you would be surprised. It's not always about score with people. It's the challenge and fun of the game.
