The problem is the E-50 is actually not very nimble at all. It turns like a truck and I've on more than one occasion accidentally rammed teammates because the thing turns in such a huge freaking circle. It has good pickup but it literally turns like the A-20.
The gun and the armor are both AMAZING, but i find myself angling it like the IS-4 which is a big no-no. (squishy sides) Old habits die hard, especially when my ammo rack gets hit.
I love tapping things with this tank though. Moving at 10 km/h into a T-59 and he loses 60 hp. I use the lovetaps to finish off tanks with 10~ hp left.
Ramming something at the full 60km/h going down hill and the other guy will lose up to 300 hp, lighter tanks will outright explode.
