T-90M (Arena-M) has just received additional ERA modules in the Client Update 2.57.1.95. Quite neat! It makes it feel a bit more like a step up over the regular T-90M; without ERA, it used to feel more like a sidegrade instead.
Reuploading this because there's been some confusion with the WIP client and quick Live updates there's been in the past hour, but at last, here it is, fully Live for anyone to see!
EDIT: AND NOW THEY REVERT BACK TO 2.57.1.90 AGAIN, eliminating the armor and making me look like a liar again and crashing my game in a match. Gaijin, what the hell is going on!?
