I don't normally post on any of these threads because the forums are just full of people complaining right now and not having actual balance discussions.
However, I just wanted to point out that nothing has actually changed for WW. You could do the exact same thing with feral flare by upgrading to the middle tier item and holding it then building other items until you had enough stacks and then just making the upgrade.
The only thing that has changed about him is how smooth this transition is now since you aren't waiting so long for it to build up, but you also don't gain some of feral flares other bonuses.
This is typical flavor of the month stuff where no one recognized how good WW was for a long time despite pick and win rates and have been clamoring for a rework only to find out he's actually good and cry for nerfs.
Two weeks ago I said WW was very good and 10 people told me he was in a terrible place with a bad kit and needed a rework.
Surprise everyone lol.
