It's sad it doesn't work with Lulu's Pix damage, seeing a constant stream of 9 pix bolts at 1.99 atsp would be hilarious. Probably worth trying on TT still ...atsp Lulu seems better there for some reason. if she has berserkers wits end Nashors and Hurricane with atsp runes, but NO atsp masteries she will have 1.985 which is about perfect for her to maximize pix. But then on TT there are only 3 targets for a very short time, so maybe not worth it?
I have seen it used well on an AD Kayle with BotRK and it seemed strong.
