Kalista's E Completely Blows Twitch's E Out of the Water
Kalista's E is currently way stronger than Twitch's E. It stacks infinitely, has a super strong slow, its cooldown resets on kill and refunds mana, and it does a lot more damage.

EDIT: Wow, this got a lot of attention! Thank you guys! And for you saying that Twitch has a trade off in that he does true damage over time, the maximum damage it does is 216 later in the game.
