Yet another nerf to Katarina
Nerfing her passive. As if Katarina needed to be in any worse shape than she already was. First you remove Deathfire Grasp and limit her bust potential. Katarina has one of the worst laning phases in game and her roaming was what made her useful. Deathfire allowed her to secure kills for other lanes and keep snowballing, but you removed the item that works in great synergy with her because of a few whiners.
Next you nerf her ult. Her ult which can be easily interrupted by stunning her, or silencing her, knocking her up (giggity), knocking her back, suppressing her, or hell even walking out of range. You can easily counterpick to make her useless in lane. But nope. You just desperately had to nerf her ultimate. Okay.
Now that Katarina has no burst potential late game, a terrible laning phase, an ult that is easily avoidable, you have to remove the one thing that made Katarina, well, Katarina. Her passive is now destroyed and gone are the days where she was useful.
Katarina was only ever useful in lower elos against opponents who had no idea what they were doing. In gold 5 people started to save interrupts for me and cc me to death immediately. But you had to nerf her into the ground cause a few baddies complained about how she was "op" and all that. Top kek m8.
