Honestly I feel like Kayle's range should always be 525
I know she has a sword but when you're E is in cooldown or not activated you pretty much lose 100% of your DPS and I don't think you'll try to go in melee to deal with the tank. I feel like she has some inconsistency when you have your E up et can DPS fully and when you're E is in cooldown and can't apply any damages (except Q obviously).
Don't you think her range should be 525 and her E just add the damages/AoE ?
