How long do you think Riot realizes the real problem with Kalista?

Will it be 5 more patches of nerfs to stuff that don't matter in her kit. Or will they finally deal with just how well her rend synergizes with her kit and build. It doesn't matter if she can single target rend somebody for 800 damage apparently and still put out about 2k in AAs. This is also ignoring the fact that later in the game kalista can throw a Q through a minion wave loaded with spears and chunk someone for 400+ and now have 6+ spears in them also she has the random damage tied into whoever she bound to that does % hp damage and has a per person CD instead of a per proc CD on champs and also procs before the AA even lands. Also people seem to undervalue how much having essentially a free smite is on objectives (I mean really, it completely negates the purpose of trying to steal objectives if you are on the opposite team). Nunu pays for his ability to control them, but for Kalista apparently it's just icing on the cake.

How to nerf Kalista to make her managable (I mean so she has room in other areas besides just slowly nerfing her mobility). Either nerf her Q damage (scaling is ridiculous on it) or go after her rend scaling and make the % hp magic damage have a CD of 6s when procced on champs (meaning she can't use it after the first proc on a champ until she waits 6s) down from 6s per target and remove the 125 damage execute on minions.
