It's a start. I could see more nerfs in the c patch

I think they're actually pretty much perfect. The CD nerf on the ult is huge, because as a support you really spend most of the game (usually, in higher brackets) in the range of lvl 6-11.

Lowering his base damage as well and the range and the talents, yeah, this is a pretty huge nerf. Of course, in lower skill brackets, it won't be that much.
