While playing Kayle, I noticed something "weird". When my E ran out, and I have started my Autoattack at the same time, Kayle autoatacked ranged, with her melee animation AND meele damage. This bug is REPRODUCEABLE one, it even works with Jayce AND Elise. I haven't tested it with Nidalee yet.
1 -> go ranged form
2 -> trigger autoattack animation
-> while you do it, switch form
3 -> ranged autoattack with melee effect and animation
This bug is gamebreaking, and i hope it will be fixed soon.
