I'm actually more worried about the change to make it not work on ranged champions.
The people it worked on - and arguably best - were the ranged hypercarries. Nobody really complained that Kog'maw with it and a bunch of AS items (hurricane, botrk, wit's end, etc.) could shred you, because it's freaking Kog'maw and that's his job. Same with Kayle - it wasn't a massive balance problem when she ran around with it, because her shtick is "I do no burst damage but if you try to win a sustained DPS contest you're going to lose. "
People complained most about it being the only damage item on melee champions (Yi, Xin, Shy) that took advantage of the high stack speed combined with Sated Devourer to be insanely powerful at the 20m mark.
IMO, they should make it 1 stack per attack on everyone.
