Damage Runes for Renekton
All AD makes him feel sloppy and it doesn't carry over into the lategame well at all. All AS makes it hard to last-hit and his spells start off being weaksauce (unless you consider the fury gain).
Maybe a mix of both would be best? I was thinking all AD marks and all AS quints. Yall think im on the right track? Would that page work best on someone like Vi as well?
