How would you say AP Varus works out?

I've only had 3 games on him, but have been fairly successful with him on all three. (At least in my book.)

Things I can think of about him, he bursts tanks as well as squishies, late game my W dealing 19% Max HP damage per stack of blight, and an AOE ult being able to deal 1k damage.

I've actually outdueled the enemy vayne late game with Varus getting I think 2 stacks of Blight off and ulting her as she came out of her ult tumble being able to outright one shot her if you wanna call it that way in her wave of baron minions. Your autos late game deal mid game adc damage since they scale of AP, and your W damage doesn't cap on minions, just monsters. So I could just one shot the super minions that came to our base.

All in all I wouldn't say he's a solid pick and probably thrived when DFG was around, but he seems far from bad. If your team can peel for you he seems to output tons of damage. Just his long range poke doesn't do that amazing damage on AD Varus.

And if it does matter a bunch I'll say it here, yes I was Bronze I last season and haven't touched ranked this season. I'd rather not deal with the stress of it.
