and Zen... go crunch the numbers on ooze/spit vs spit and run. Compare damagegiven/taken for both builds, agaisnt a common oppenent like erebus. Don't forget to apply mana cost which can lead to no grasp, and loss of melee when chasing. Also, say your chasing an oppenent, who sigiled and was running away, your spit is at 1500 now, and your oppenent has 1300hp left. So since youve been spitting to bring his hp down this low, you have 900 mana left, and spit one more time. Now your oppenent is far enough away, (and you have no mana for grasp) to quickly tp to crystal and live. Where if you spit to begin with, then oozed, then chased, and grasped when he tried to tp, then spit again, he would be dead. I know all situations dont happen like this, but it's quite common with a few differences in different games. Non Ooze builds are for PUUSSAAAYYSSS plain and simple.
well without the spit you have no big burst damage. The problem with auto attack is it's too predictable. If you don't get spit, you will take more damage fighting an Erebus, he can bite you more and heal more with his monks. He would probably not even have to run away, but you. And with the mana, 1 helm and unbreakable boots should really be more than enough mana.
After last night, I'm not sure if there is a counter to a pro ub, but another pro ub.
