Would it be OK if Katarina was healthier?
My friends disagree with me that she would be a problem, so many of you might as well, but I've always felt that having a Katarina on the enemy team is super frustrating. The main reason is that when she is ahead she can blow several people up in the blink of an eye, with no window to respond. Her abilities not being dodgeable and Shumpo having zero telegraph doesn't help much. The Katarina's skill matter so much more than the skill of her victims.
My friends say the "counterplay" is just "don't feed her", but often that is out of my hands, and after she gets a few kills it feels like all I can do is to stay as far away from her as possible.
I get that her ult is easy to shut down, her laning is weak and she can be very binary, so there's a lot she has to play around. But I'm not playing in diamond or anything, so there's no guarantee someone will be attentive enough to CC her the second it's needed. I would still have appreciated something like 0.5 sec cooldowns after a reset, even if that would make her clunkier. Right now she can just hover her mouse and spam her abilities hoping she kills something, and with a bit of luck that will secure her a multikill. She barely has the split second to make a split second decision herself. But then there's scrips...
I don't mind her getting buffs or new tools to compensate, it just feels unfair when there's no chance to react once she has found an opportunity to go in.
