Garen's changes in a nutshell
"We wanted Garen to constantly change targets to people who are probably carries and squishy af so he can do maxhealth% which would probably be equal to about 15-30 damage throughout the game(minus armor), and make him think, "My true damage can kill this guy," then changes back to magic and they get out with 100 health, FOR DEMACIAA!!!"
Edit: Oh yes, sorry, he does true damage 15-30 damage. Woot woot
