imm i think ooze spit grasp build hp stack is even worse shadow
You can't do both at full strength effectively, at least not early enough for it to matter.
I'm confident that it's fair to say that >90% of people who think spit is OP are people who started running away too late and died from spit as they futily tried to limp back to base. That seemingly futile situation enraged them to the point where they became emotional about it and thereby deemed spit to be clearly OP.
If their opponent had specced inner beast, diseased claws, ooze and foul grasp, they would probably be even MORE annoyed by how they can't outrun this monster (diseased claws + inner beast), can't beat it at melee (ooze reducing their attack speed) and can't tele out or use their slow as hell nuke skill (foul grasp).
