Kalista-Syndra
Kali- When I started the game I had 2 oaths going and about 5 mins in they both disappeared and I had to redo the thing with my support. I can't seem to make this happen again but, I found it rather odd. Also the dash seem extremely buggy. Before 5.1 I was rather good at it and now it doesn't seem to be working much at all. I doubt it's me, it doesn't feel sensitive enough. That or the new AA target switch thing you added is killing the time left for a dash.
Syndra- Her new E is extremely buggy, my orb hits them dead on and no damage or stun. Sometimes I only get the stun or the damage.
