Careful Riot , you're walking on thin ice
I would like to speak a little bit about Aatrox and especially about his hotfix that he got some hours ago .
His heal now is dependant of his missing HP . And you just increased his base HP by 43 points . People are still experimenting with stuff , and runes .
Flat hp runes + veteran's scars and d.blade give him 782hp lvl1 and hp/lvl 722 hp . Some people may even start with a ruby crystal to get 850hp at lvl1 .
My suggestion is : Increase Aatrox base HP/pool from 538 to 560 and his growth per level from 85 to 90 .
