Katarina?
Now i get that if you don't know how to play Katarina, you'll probably scrub yourself into death. That being said:
These two not long ago we're hated so much for their kits (outplay potential, mobility, burst).
has more than both of their pre-reworked forms combined.
She requires no mana or resource to manage other than cd and ability placement
She has an aoe slash that can be activated multiple times in annoying succession and has a pretty decent dmg range.
She has a powerful poke that instantly turns into kill potential in most scenarios
Her ultimate is high dmg, great in 1v1 or teamfight, and has a reset mechanic. Her ult doesn't have a knock up condition, she can cancel it and escape, and even without reset a low cd.
Her snowball potential makes
look tame.
Overall I think she's reached an unhealthy point of strength. Its easy to say "heavy cc beats her", but her mobility makes them hard to land AND if she's not soley cc'd and focused its pretty much freebie for her to escape or re-engage and kill you instantly.
The new GA is a go to item to help with her sole weakness of little health and being cc'd. She can get gunblade 1 base ap item (wand) and then GA and she becomes a monster you have to cc and blow up twice.
If you disagree that she's overpowered, please explain why. I've seen some champs able to fight her, but then she just goes to another target and 1 or 2 shots them to get ahead or catch up. My last few games that have had her (aram or otherwise) she carried HARD and pretty easily too. I clocked a quadra from a kat at about 3 seconds in dragon pit. She ulted the last target and had the triple just off of blade bounce and aoe dash once. She moved right through cc. Shields/abilities did nothing to mitigate the burst. She went behind in lane, only had starting item, hextech and boots. She backed, got GA and went 16 2 X. We'd stun her, get her low on health but her heals from the burst would put her at full health as soon as she was done being cc'd. This is only one example of the many since her rework and it never feels like you can do anything about it. Its just worse with GA now.
TLDR
I feel she should require energy or mana as a way to nerf her constant flow of power between skirmishes. At least give her a cut off valve of "i've used too many abilities too fast and am out of resets" OR a longer non-resettable ultimate time.
I'm not asking her to be completely gutted or anything, because taking away too much just leaves another unpicked champ. maybe nerf her scaling? nerf her synergy with GA?
got nerfed for being overly mobile bursty and hard to kill, why not her?
Is there any other talks about her going on out there? Any hints from Riot they've got her in her sights or on the radar?
