Well I got the T30 finally, I have to say it's quite a change from the T28 Proto. Faster and a much bigger gun but squishier in some ways. So it's been a learning experience. With the Proto I could go and bully tanks and use that good rate of fire to just melt them down while bouncing a lot.
The T30 gets some huge numbers on hits though, great gun with a little wonkiness to it but I'm still getting my crew to 100%. At like 94% now. So I'll with hold judgement on it until I'm maxed again in that regard.
I will say melting down tanks in 2 hits is amazingly fun or even hitting some big ones in one hit is fun too. A poor KV-3 popped out and got one shotted with a solid side hit to him while an M103 learned to fear the doomcannon as well.
I'm just playing poorly with it though because it kind of tricks you into playing it like a heavy tank where you get chewed up by the rest of the faster firing better armored tanks in the game. But I'm learning to stay back and do what it does best, put the fear of God into other tanks and keeping them back.
What skill/perks are your crew using? Apparently we have to start taking that into consideration now too when it comes to performance in some ways.
