I don't think for one that it really helps AP Varus.

The magic damage on-hit synergizes well with Wit's End and Nashor's Tooth for AS-AP Varus, so you're taking away a significant amount of DPS (even full AP Varus will feel the blow because autos just won't deal damage anymore). The fact that you can't just max W and have your max % health damage at level 9 means you also don't have quite as much as far as midgame power spikes go. Sure, you can detonate Blight more frequently, but I have the feeling it just won't deal quite as much damage and it actually doesn't scale that well for lategame, so AD Varus benefits much more from this. I'm not even too sure of what you'd level up first as AP Varus, but he suddenly becomes even more reliant on Blight detonations than he currently is.

I'm also not too much of a fan of the new W. It's not bad per se, but it sounds like Q w/o charge with an AoE strapped on it.

On the good side, Q's change is very welcome for both AD and AP Varus and I like the idea behind E even though global range is a bit much and I don't really like the fact that damage only triggers at the end.
