First off, learn to use the damn quote feature. It's annoying that you can't figure out how to click a button properly.
Towers deal more than 170 damage if you are at lvl 6. You would be taking at least 200 dps per hit from tower. Most smart players would probably have 3k of HP if they know they are going against a beast. If you think you can charge in and kill somebody with at least 3K and tanking their tower at the same time. That is sucidial.
It's called "armor." Scalemail + Narmoth's chestplate = 170 damage dealt by towers. Killing somebody with 3k HP? Obviously not (unless it's reg, or TB not using skills, or Rook without a tower farm; there are really a lot of exceptions to this!). But unlike a spit build, if I've been fighting somebody towers will not deter me from continuing on to the kill. You might want to read what I say, and not assume I mean "LOL CHARGE AT ENEMY TOWER NO HURT ME!"
This is where mana management comes to play. There is a time to use SPIT or not and this is up to the players to decide. 3 lvl 4 SPITs + Ooze do enough damage to kill any player with 3K of HP.
...and? If you spit somebody three times to kill them, and they teleport away, you have NO defenses less. Yeah, you have Ooze, but you are behind on passives. A lot. You just won't be able to handle it. Even with perfect timing, you are going to need more than three spits to hold off your enemies for any decent amount of time; with what you've suggested, you wind up having to go back to the crystal for mana as often as you actually push enemies away. Not a good thing.
It's very most likely that you will engage with your opponent . I havent had a game where I didmt fight my opponent within the first 5 or 10 min of gameplay. It's bound to happen. Hence, by having Spit/Ooze you will have more ground. I played against some Ooze UBs and most of the time I found them to have about the same amount of HP like I have. 7K-8K.
Very most likely? To quote the internet, 'lolwut?" Anyway, if you are relying on your opponenets being dumb enough to fight you when they don't have a chance, then your build isn't good. If you only get kills because people are dumb enough to run in after spit, then... yeah, it's not going to work out that well. Also, you only have 7-8k hp because you don't buy any mana items so you can't use spit anyway! You are just an Ooze UB without stats or passives, that sometimes gets to throw around a spit and run back for more mana.
People dont run away with wand unless they are low on HP. Guess what? Since you have Spit, you can immidiately SPIT them the moment they run or SPIT them while you are chasing them with your wand + 5% slow on them. If players do stack SPEED GEAR, they will be low on HP instead cuz they dont have gear for HP. In this case, they will die the moment you get into melee range with them. Even if they have natural speed buff, your Inner Beast + Wand will make you faster than most demigod in 7 secs.
Once again, relying on the opponent being stupid is a bad idea. You can't "immediately" spit. You don't have enough mana to always spit everybody who is running away. And what the hell is with the random capslock spam? Anyway, you don't need to stack speed gear to escape a wand of speed. You just need a wand of speed of your own, and a passive speed buff/debuff. Oak can escape you just by using pentience plus wand of speed, Erebus can escape with bite + wand of speed, TB can escape with ice + wand of speed.... actually, about everybody except Rook can escape with just their skills and wand of speed (even with the 5% debuff.) Also, how do you have inner beast AND diseased claws? For a spit/Ooze UB, that is actually impossible. You only have one point to spend on passive skills until level 10. Not only that, you get your passive skill at level 8. You are going to either have to wait until then to be able to chase people down, or make the build even weaker by delaying your damage skills.
Ooze is completely a melee build that requires you fight head to head which you will lose alot of HP whether you can run away or you kill your opponent. Not having HOL is just a bad idea. This saves you time running back. And I'm not saying you need to max out diseased claws out. With my build, at lvl 11 I have Spit/Ooze maxed out and other passive skills.
And? You can't kill people just by spitting on them either. You still have to go head to head to take a lot of damage; spit really isn't that effective when you only have 3 casts. Also, 3k is not the average HP at level 10. Maybe average without equipment, but generally by that point most people have 4~5k HP. So your three spits would have to be burned fighting ONE person to the death, and then you would be an ooze build with less passives. Not that great.
Basically, your build is just an Ooze build that swaps passives for Spit. With no mana gear at all, you are not going to have any chance of spitting enough to win fights, let alone being able to interrupt and spit (which is actually USEFUL for team play) plus without passives you won't be able to help your team as much. You are good for single 1v1 demigod fights, but whether you win or lose the fight, you will always have to pull back for more mana (or have Heart of Life, which is hard to get by level 10 with such a weak early game unless the enemy is feeding you), and you can't really support your team.
Also, on Heart of Life: How is it useful? It doesn't increase my max HP, and I get way more HP/s from Narmoth's ring than I do from the HoL. Sure, the HoL gives me a huge heal out of battle... but as an Ooze UB, getting out of melee range usually means I am losing so badly I should be running back to the crystal. HoL is great when you have mana needs, but when you don't, waiting 10 seconds for 3k HP is not really preferable to having the slot open for Sigils of Vitality (instant ~4k HP), flag locks, or TP scrolls. Ooze UB is one of the few builds where a HoL really isn't that useful.
