Olaf
As long as my beloved Olaf doesn't get any more nerfs i think we'll be fine Riot, if anything olaf is still ok hes one of those champions that requires a good team to play around and if you have good communication then everything will be fine. If anything really he only needs a visual rework and maybe a change to dances and taunts on his brolaf and pentakill skin, but thats just me riot.
olaf is the type of champion that can build all tank and just soak up damage or all AD and peel for the carries or bruiser and be efficient enough to help. no nerfs needed no buffs needed but again that is just me.
He's been one of my favorite champions since ive played him and i really hope he doesnt get nerfed anymore <3 thank you riot :3
