The only real big issue with Darius (Not a rage thread)
TL;DR: This isn't actually a rage thread. This is an actual problem I've noticed when facing Darius that leads to both clarity and counter play issues. If your hitbox is mostly within the inner ring for his q but a tiny portion is in the outer ring he'll always get the heal and bonus damage.
The issue is that most top laners have a large hitbox. Seems like a weird thing doesn't it? Well here's the thing, if I see that I'm gonna get hit by his Q and there's no chance of me getting away from the damage, then what should I do? Oh ya, walk closer to him so the damage is lower and so he doesn't get the heal! Oh wait, pretty much every melee top laner has a big enough hitbox to their model that, no matter how close you get to Darius, a part of your hitbox will be in the tip range, meaning he'll always get the heal and bonus damage.
Can we just make it so that if most of your character model's hitbox is within the inner ring you take the reduced damage, and if most of it's in the outer ring he gets the bonuses? Because nothing is more irritating than standing in the "This actually tickles" zone and having him heal and do increased damage to you because the ass end of your hitbox is in the dunk zone.
