I know that this is a rare issue, but if someone earns 2 levels without spending them, then spends a point into a skill they can get again, there's no animation to indicate they were successful - the available points just ticks down one. This could lead to them clicking again because it really feels like that first click didn't work.

So some kind of animation, be it a flash or the tab going down then popping back up, or whatever, would really help provide feedback here.

I have another problem when i level up twice. in dota when i cast a spell on myself i.e. omniknights heal, i click the chars portrait so i dont have to find him in the mess. In lol i do that too, but if i leveled up there is a number covering my face. if i level up twice i have to either find my char in the mob and possibly misclick or decide which spells i want right away then cast the spell on myself. there should be another way to indicate that your char has leveled.

as far as self clicking I would love to be able to use the alt or another key to automatically cast on myself...
