His E only provides safety if your target stays in the AoE while you stay back -- in other words, if everything goes right. Varus still remains squishy and immobile, so while this would provide great situational range, it wouldn't be oppressive or unhealthy in any way.

The point to percent health damage is that it affects all targets equally: tanks and squishies fall in about the same amount of time, which is one of the unique features of AP Varus's damage even now, and I think it would be best to focus on that part of him than give him an autoattack steroid he can buy anyway. I also specifically added CDR on Blight detonation to make Parting Shot usable multiple times in teamfights: detonating three Blight stacks with the ability alone brings down its cooldown to 7 seconds, and with cooldown reduction this bonus becomes even more valuable (there's also a lot of potential synergy with Runaan's Hurricane). I also disagree with making Desecrated Ground a DoT, because the emphasis should be to detonate three Blight stacks at once each time, not just proc them as they come. I also think Parting Shot would be enough to solve the issue of inconsistency, since Varus would have more actives to use in order to detonate Blight.
