Why WW is balanced and should not be nerfed

This is responding to numerous threads on reddit moreso then the offical league forums I just prefer posting here since I am sure most people viewing this view each message board.

By not nerfing WW riot will make the playerbase better in general by forcing quick reaction interupts and in turn improve against kat players, now I realize that WW is one shotting people in his ult +q but kat is no different she just cant stun for 1.8 seconds, and of course she one shots whole teams by face rolling. I believe by allowing champs like kat and WW to exist in their current state the playerbase will either get more skilled or just those that can will improve but either way I believe that the playerbase of top tier will become stronger and riot needs to balance around the top rather then the bottom, and I have not seen any top tier player say anything besides WW is top tier in solo Q atm.

WW can be cc'd slowed and has no skillshot dodge while doing a lot of dmg, Yi has immunity to slows and can dodge skillshots easily with well timed Q's so why not nerf Yi over WW? I actually think both are in good place's, they are champions of solo Q carry jungle's that sadly won't see much competitive play. If WW is played overwhelmingly in the LCS spilt, or OGN with a high win rate then nerf him but he isn't the issue the issue is the skirmishers which is nothing in a teamfight, but he was still rising and with the new jungle will be even better but thats what riot wanted. The non-sustain jungles are high risk high reward while WW and sustain jungles are safe picks, Nunu being an exception hes sustain with high risk high reward due to lack of scaling and needing to use his snowball, to snowball lanes :).

All in all, Warwick deserves no nerf, maybe the skirmisher jungle item does but it isn't very strong except on a few champions, WW and Yi being two of them. Other games require top tier reaction interrupts now even though league is a lot of skill shot based it should encourage such outplaying and skillful reactions more and more, not less and less.

P.S. I noticed none of the duo q players, none of the ones I recorded anyways, who duo'd with the botrk exploiters were not banned, not very hard of a ban hammer Riot since they all played 4-11 games knowing they were duoing with an exploiter for freelo.
