Kallista's Spear - Needs a Very Minor Tweak
Ask before you bind someone. Just... ask first. It takes 10 seconds, most people won't turn you down... but do not just grab the nearest tank or bruiser and force them to be your ult puppy.
The fact that you cannot deny this ability is almost a troll on RIOT's behalf, since you are -literally- giving one player control over the life and death of another. I honestly believe that, when a Kallista attempts to cast this on someone, it should give them the ability to deny or accept. Otherwise this is quite literally forced gameplay, and puts them at the beck and call to be yanked around during team fights, or when ever Kallista feels like it if they are trolling.
