Guys I think i have a solution for Kalista!
Instead of her passive giving her a dash, Riot could make it so that auto attacks dont stop her movement i.e. she can auto attack and move at the same time.
This would still help her kite and chase but it wouldnt nigh on impossible anymore to stop her doing so as slows would actually effect her and she wouldnt be as hard to hit with skill shots (cc).
This would definitely be a nerf to her as it would reduce her mobilty, but I feel it is necessary as she excells in too many areas right now (kiting and chasing,objective control,wave clear, burst with her e, utilty with her ult and w, poke with q,amazing multi target damage with runnans) and i feel she needs to have a clear identity other than being extremely good at almost everything.
I also feel that the mobilty she gets from her passive doesnt have tangible cost to it while other champions do (lee sin has to hit skillshot or use up wards, kassadin has to use a million mana, zed has to back off while his shadow still last, etc) while also having to work around cooldowns (get cdr, time engages/save mobilty for kiting or escaping) and the fact that most other champions mobility takes up the space of an abilty or have certain requirements (Rengar). This fact alone ,imo, warrants a nerf or compensation for kalista's mobility.
I hope I have made it clear as to why i feel kalistas mobilty should be nerfed and i hope the solution i proposed is not too confusing/wierd to comprehend or implement, Cheers!
