Her lane phase is not as garbage as people claim or predicted. I've faced a few Kayle's now who've got some experience, and now they usually play safe enough that I only get about one kill during lane and they are usually only down 10-20 can by about lvls 11-14, which means I technically LOST LANE in those situations and she is usually even with me in power before even hitting lvl 16. Mind you, I don't play riven or teemo or anything, but I play a lot of Darius and some nasus, and now that have had time on her, I have an incredibly difficult time getting ANY kills on her. With Darius I've tried ghost and ignite, and with nasus I go ghost. In either of those cases I hardly manage a kill, and she tends to get camped, but even when I get it help, unless it's a super aggressive diving ganker, it's hard to finish her off. Then she just uses corruption pition to heal back up her Mana and ho reserves and continues to poke/farm the whole lane phase while gradually and safely scaling into a monster. And trust me, I also play Kayle (I'm merely decent), and I have to agree with Moody's characterization. She is VERY safe right now if the player chooses to be. I think her late game potential is actually pretty fun to play as and terrifying to go against, but I have no problem with that. Instead I think they should reduce some early game sustain or increase her E Mana cost by like 5 or 10 so that she can't constantly harass and farm.
As it is when I play Darius, she merely pokes and farms out of reach and if I approach her she easily lands her Q and uses W speed boost to get away, then I eat a ton of damage for nothing and generally miss my E pull due to the combination of her ranged slow and her speed boost
