The Experimental Kayle changes on the PBE are a good change
For those of you who don't know what they are
Level 7: Ranged basic attacks (525 range)
Level 11: Fire Waves
Level 15: True damage removed, range increased to 575
These changes make Kayle's early and mid game far better while also toning down her late game. Overall I think it's a great way to balance her out.
(It's one of the only good things going on rn)
