I used the IS2 a lot in previous patches (was actually my favourite unit) but I do not like its current iteration.
I liked its uniqueness with its long reload time and high damage and I had no issue with its AT capabilities. Relic however seems to want to make it more of an AT tank which is a shame really, as the only real threat is the Tiger tank (may change with the new armies of course)
I find it has around the same effectiveness in a match up VS a Tiger as before i.e. it will still lose, and it has lost effectiveness in all other roles (not to mention a fuel increase)
Its old AOE should have been nerfed a tad, but that was all that needed doing really. "If it aint broke, don't fix it" it as it were
Molo has been doing this for ages, it was snipers and guards in cars to T34/85s before, now it's engineers and guards in cars to T34/85s. It's not that hard to deal with because you know exactly what he is doing, and he doesn't support it that well (tends to not bother with map control and tends not to lay mines).
Yeh I guess the shock is a factor. So what... panzershreks?
