Sooo, why is Voracity a thing?
Yes, yes, i know: another Katarina complaint thread.
But seriously: Voracity is the only reason, THE ONLY REASON, this champion is even complained about.
Voracity is Kat's reset mechanic. All her basic CD's reset and her ult CD is reduced by about 20-25% on kill or assist.
The assist bit is what I find incredibly stupid. She doesn't need to kill anyone or even land her ultimate to reset her entire kit: she just needs to do a teeny bit of damage and have someone else kill for her.
This basically removes any point in counterplay for Kat: Sure, your tank or someone can CC her out of her ult, but it doesn't mean anything unless she dies. If she doesn't die off that mistimed ultimate, her team can capitalize on whatever damage she managed to do and potentially set her up for another full combo a few seconds later. It's not hard to kill a squishy with 60% HP, and doing so gives Kat another round of Bouncing Blade/Shunpo/Whirling Steel, potentially giving her another assist or even a kill (and resetting her basic abilities again.)
She should be rewarded for kills. She should not be rewarded as much as she is for assists, she's equally rewarded for kills and assists right now which isn't balanced.
My proposal is to increase her benefit from getting kills but significantly reduce the benefit from assists.
Voracity (changed): Kills reduce Katarina's remaining cooldowns by 15 seconds. In addition, Katarina gains +10% damage for 5/6/7 seconds after scoring a kill. Assists reduce Katarina's remaining cooldowns by 7.5 seconds, but do not grant bonus damage.
Alternatively, she could gain a different/stronger effect for kills and not gain any benefit from assists.
