I find the Löwe buff to be very similar. All it needed, in my eyes, was better mobility. And then they buffed its mobility, armor and gun depression. It gives me the feeling that they are in the process of buffing a lot of tanks to even out the scene. But maybe that is overestimating..
I do want to try the Lowe, but the cost is keeping me away, as always. I might be able to talk myself into 30 USD for the Rev, but twice that for a Lowe is too steep for me.
Heard it rocks though, so if there's ever an opportunity to win it I'll definitely go for it.
