Ah, now that's interesting. Your characters don't quite know yet.  Instead, you have to figure out your character's limit for damage. If you noticed, Liam (Nasus) probably has more health then say Vel'Koz or even Shyvana, but can't output the damage as such. So if you play a squishy champion, hits probably hit you alot harder than a tankier champ.

Edit: Also, post up your CS in the Character Tab.
