oh god please get rid of oathsworn
I just had the misfortune to be Kalista's Oathsworn for the first time. It was only a bot game, but the feeling of lost autonomy was appalling.
Is this supposed to be teamwork? Because really it just feels like being a slave or puppet. There is no teamwork here, its just Kalista BMing an ally.
Oh, you wanted that last hit? Too bad, Kalista W passive gives her the credit. You are about to kill an enemy and you need the gold? Oooh, sorry bud. That little marker over their head was too much for Kalista to resist attacking. Oh, you were about to turn around a fight at low health? You didn't need to be saved? Well too bad, Kalista wants to use her fancy knockup.
Oathsworn is an idea that a kit should be built around from the ground up, not tacked on like it is on Kalista. Remove it, give her a new ultimate, then build a dedicated support champion from the ground up with the Oathsworn idea as their basis.
