Who upvotes this shit. I mean yeah she is kind of strong early, but still has lots of counters, assassins are getting buffed next patch, she might need some mana nerfs but this imbecile asks for late game nerfs on a late game champ. Why don't you look at Fiora and Cait, they have the Orianna problem times 15353109681386194767914764997417691, if they don't get any nerfs, Ori shouldn't get any as well, and I hate to disappoint you, but they aren't getting any significant nerfs so far on PBE. Ori is a problem, but there are at least 15 bigger problems atm.
As for the competitive play, they like to keep Ori strong for worlds because she enables a lot of team comps and brings diversity into the game and also those exciting moments when she hits a huge ult. I am not a supporter of that though, I would have double standards if I did support her being kept strong just for Worlds since I firmly believe that Lee should get reworked or gutted at least and RIOT stated that he is kept strong for "exciting pro plays".
