A Kalista Buff Suggestion
yasuo's niche is relatively similar to kali's in that they both rely on high mobility to get their jobs done. The problem that i kept running into when i tried to learn her or practice with her that most dont really have with yas is that its pretty easy to lose track of your target in a crowd. yas can just poke through everything w/ his Q if he feels like it but its so easy for kali to lose targeting on her intended victim while hopping it just feels pointless to even try anymore.
I know there has to be some champs with a high skill cap to get that feeling of skill but for a free to play game this champ is just in a league of her own in terms of learning and tedious micro-management. Which brings me to my suggestion.
for those of you who have played tracer in heroes of the storm have you found her overly difficult to control and direct once you've practiced a bit? I know i haven't and I think its due in part to her unique auto attacking mechanic to lock onto her intended target as shes moving. I think if Kalista used a variation of this lock on mechanic she would regain some popularity and be a tad easier to use while hop kiting.
Basically, when you select a target for kali by clicking on them they gain a large target under their feet that kali and her teammates can see. When she's in attacking range of her target her basic attacks are focused on them. If she isn't within range of her target she simply selects one of the nearest enemies to her to auto attack instead as she hops around as she already does if you don't consistently click your target and keep close enough to them.
I think this sort of mechanic would take a huge load off the players shoulders as they navigate kali through and around team fights. Plus it can make the players intended target bluntly apparent so their team can act accordingly.
