AP Varus update? Please!

For right now, AD is currently favored on Varus because you don't need to skill shot his basic attacks. Also, Q has pretty big damage potential.

However AP Varus deals MASSIVE damage and can be a HUGE late game changer.

With 3 stacks of blight on an enemy, you can deal >32% the enemy's max health PER skill landed when near full build. (3 enemies at a time with Hurricane) Which can make him a stronger tank-destroyer than Vayne.

The main issue is landing the skills after blight is stacked. It's just too easy for most champions to evade him. Which makes landing a skill shot to consume blight more than just difficult.

However, all he needs is 1 or 2 adjustments and he could become one of the strongest AP champions to date. I've had a few ideas for changes, but you might be able to come up with better ones. Here's what I got so far:

• Make blight stack on Varus (between skill casts) instead of on the enemy, and then apply to all enemies hit with skill. (Would remove the need for hurricane)
• Change E to direct cast instead of being a skill shot.
• Change Q to only be a skill shot on enemies who are outside a 25% charge range
• Change R to automatically consume the blight stacks on all enemies without having to land. (Can be done with either Q or E as well)
• Automatically consume all blight on all enemies if 2 skills are cast within "X" amount of time; or if 2 skills are landed on any enemy(s).
• Increase Varus' mobility (Faster move speed, "X" Amount of move speed per blight stack on enemies; teleport to target if Q lands; or something of that nature)

Any one of those is all it would take to make AP Varus become a regular thing.

But that's just what I have so far, I'm happy to edit your ideas into the list if you state them in the comments below. Go easy on me though, I only just had the thought of suggesting changes for AP Varus today.

Whether it comes to fruition or not, thanks for reading thus far at least.
