Kalista and some needed changes
First off I would like to say I love playing Kalista, but I think she's really on the weak side. Especially in the Yasuo, Irelia, Jax meta etc.
A few minor needed changes,
First: make her auto's deal 100% ad to minions and monsters. You have no clue how many cs I have missed because I have to calculate 90% of like 123 ad. Or just cauae im so use to csing on othed adc's so I think I deal enough damage to execute it only to find that it had like 2 health left. Hah
Second: Make sentiniles remove slows when she casts one. Basically it takes the slow with it. This would help A LOT. A high cd on sentiniles so it wouldn't be tooo broken.
This I believe would help her but not completely break her.
