While I've watched Jingles and Quickybaby play on streams and Youtube, plus I have a friend trying to persuade me to play, I'll probably wait until the British are added. If Wargaming treat the British lines the same as they do in WoT, then I'll give it a pass, something I know I'm not alone in deciding.
That said, it does look decent, although the potential for TKing trollage is high. I expect a lot of torpedo spreads will be "accidentally" fired so that they hit friends rather than foes. One thing I really did like is that the disparity between different tiers doesn't appear to be as important as in WoT. Admittedly that may be because the majority of games I've watched had been mid to low tier, and it may change greatly with the higher tiers, but it seems that a low tier ship that somehow finds itself in a much higher tier game can still be useful with even an average player.
