I think RIOT have given up on actually balancing things, now they're literally just looking at win rates and making pointless nerfs.
I main Wukong, I have nearly 4 million mastery points with the champ and I can tell you, if you touch Wukong you'll only be giving him more of a handicap, he loses most normal match ups in the top lane and he's mediocre at best in the jungle... nerfing his damage, especially his E is unnecessary and plain stupid.
There are items in the game that completely render Wukong useless, not to mention counter picks like Lulu, Janna, Darius, Garen, Cho'gath practically most tanks... I read some adcs/supports perspectives on this and they are out right funny, if they can't hit R or Q fast enough then that's not the Wukongs damage or combo problem, it's there own, I've tried to get a combo off in team fights on the opponents adc countless times only to be given a slap by a Janna Q or a Thresh E or a Lulu R...
Items that counter Wukongs "burst" is simple, Steraks gage, Zhyonas, Hour glass, there are soooo many counter items/champs you could intelligently build to counter most champions in this game but no no.. that would mean people would need to use their brain and build to suit the situation and that's just WRONG! How dare you have to change your build path in a game!
ADCs are glass cannons, they could just as easily 3 hit a bruiser or a support if they had the same level/item advantages as a top lane Wukong plus ADCs are ranged, if you main ADC, don't cry, this meta is what it is and another reason "Wukong" has stuck out like a sore thumb is simply due to this current shitstreak of a "Meta", I hate using this word but if you're going to play APs botlane or some other cheese squishey smite botlane tactic then you're going to get 3 shotted by assassins, simple as that.
Perhaps Riots balancing team should understand these points and keep this "nerf" where it belongs, in the circus of a mod (PBE) as this potential nerf is only going to destroy Wukong and then force a rework which 9 times out of 10 ruins any champs "feel" and "nostalgia" they once had.
Leave Wukong be, it's the players that are retarded and don't know how to build, it's like how often within the bronze to mid plat games do you actually see someone building an Excutioners calling against a Soraka, hmm well in my travels from bronze to high plat I've not seen ALOT of these players, but its the players that DO build these items who excel from the rest... eventually.
If ADCs or Supports are the actual reasons for this potential nerf then let me give you guys a tip, build a Steraks gage or Radiuns, Oh noooo! I hear you say? This game is a tactical game when played properly, if you want to win you'll build adequately to do so, it's as simple as that, Steraks counts the "burst" and trust me, you will not get "one shotted" or Randiuns omens active slows Wukong down which is always a nightmare for us, use your brains.
