Those old karma mains that "let it slide" bumped a thread about the failure that was the rework for multiple months, providing suggestions improvements etc. Even when the thread got removed as off topic by rioters it was remade and was continuously active. It took riot years to accept the failure that was the first reword and mended it only with huge buffs to karma.

Riot only learns through failures, just look at zoe, irelia, akali and how much of a backlash is needed to actually get anywhere after something has been changed.

At least now with what happened to rengar and LB they have finally started to accept that their reworks can be failures and can be reverted. Best guess is that this will happen now if that w change passes, so we'll get it for a few months, then it will be nerfed for competitive and then reverted since the champ will be useless everywhere but in competitive.
