Stop calling it nanonerf. It was "fixing horrible broken server synch that had everyone warping and teleporting all the time". If something was moving more than 50meters from you, you had near 0 chance of hitting it. You could snipe or arty only at perfectly still tanks, because if they were moving it was near guaranteed that where you were seeing the tank was not where the tank actually was.
Yes it was interesting for some tank types. Everyone was zooming around , tier spread was huge, but due to age of the game and server population at time there was a handful of T9 and T10 tanks and T6 arty. So huge tier spread could work.
Now while I haven't played 7,5 test yet, I do agree that this will make game more boring and make armor near irrelevant @ T10, especially with new TD and med guns. Otoh it should be nice for T-34s and derp Shermans.
