Kalista's win rate dropped by 5% after the last patch
AND YET, they don't address her main issue, which is her retarded objective control with rend
Srsly, that is unnecessary ( and useless in solo queue) power that is forced into her kit
YOu could make kalista deal 1 damage with an auto-attack and she'd still be picked in the LCS
Her sentinel "soul" has such an absurd range, 5000 RANGE! just WHY.
If I wanted a champion to scout out the enemy, I'd take 
The nerfs to her auto-attack damage is ridiculous....
Actually, what does Riot want Kalista to be? A lane bully? but they just nerfed her sentinel damage A hyper late game carry? But with 90% AD scaling, kalista loses more games past 40+ mins Ridiculous self peel/uncatchable? But slows affect her dashes ( yes, even ms slows)
It's just ridiculous when riot has no idea what they want Kalista to be
ok
to be a much much better pick even in mid-game spikes while scaling much better towards late-game
+ her range actually sucks, and the majority of the tanks now have ways to tell her to fuck off due to the new tank items. On top of that, she does 10% less than other adcs, and 20% less if she builds crit so around the 30 minute mark she's only 80% of an actual adc. Also, it is a lot easier to catch her now due to the nerf to her back step. Anyone with a single speed boost can catch her, or black cleaver, or triforce, or slow. It's not even difficult anymore. Hell, Vayne actually kites better than Kalista now.
shouldn't even be viable. Like, no. You can't have all that and still have strong laning, decent midgame and lategame. Just nope. It's too much.
or DEFINE WEAKNESSES. PLEASE.
