You were able to dodge PE AT nades in CoH. I think it would only make sense that a mindful player could micro a vehicle to dodge an AT nade in CoH2
It's and AT nade in name only. It's just a repackaged sticky bomb. It always hits and it is apparently designed to crit engines... All they did was change the name from "sticky" to "AT nade" to try and cover up the fact that they were lazily "phoning it in" on some of these abilities when they simply copy-pasted them from coh1.
Whenever you see "AT nade" in coh2, just picture "A Sticky Bomb by any other name" and you will feel better.. the fact that the animation doesn't stop/cancel if you move out of range is lame tho.
