Don't care if I'm double posting I guess I'm going to have to spell it out to GD why his E is so important.
Varus' other abilities detonate Blight, dealing magic damage equal to a percentage of the target's maximum health per stack. Maximum damage capped at 360 against monsters.
Blight's description says his other abilities detonate blight.
Varus fires a hail of arrows that deals physical damage and desecrates the ground for 4 seconds.
Now read carefully. Yes his E slows, but it's not that that makes it so useful. It desecrates the ground for 4 seconds. So for every second your enemy is standing on it, you can auto attack and Blight detonates automatically. I can't tell you how many times I've used hail of arrows when I am right next to someone and watched their health melt over that 4 seconds.
