Why does Ulaman do this to me

I spend 20 minutes trying (and failed) to kill Ulaman, the sovereign of the Well in a t13 map.

I go in, he attacks with melee 5ish times. Disappears, spawns adds spams his BS balls then he heals for about 10% hp. Rince and repeat. Is this bugged or is this fight just shit, why does he keep spamming the same abilities over and over again?

I get him to about 80%, he comes back with 90% and him disappearing screws my rotation so badly that i'm lacking dps to make up for it before he does it all over again.

Disappearing is a part of his fight, he will disappear 3 times while you fight him.
When he disappear (transform into a shadow form), you need to follow him behind the gate he just opened and destroy the Abyss pillar in a limited time.

Need more DPS.

That's not what i'm talking about, he goes invulnerable and disappears when he summons his adds, then he reappears with more health than when he disappeared and he is not supposed to heal.

The answer is always more dps, but i've done this almost every league since this content was added and i've never had problems, i've done this with less dps before, also the dps race is the spires, not him. He's not supposed to heal and your dps on his part of the fight, is not really supposed to matter.

My problem is not my dps, my problem is that he was literally healing himself and he's not supposed to do that, and he was disappearing and healing at a rate where i couldn't kill him. I am asking if i encountered a bug, because i have no memory of this boss being this way. We're talking he disappeared every 10 seconds or so to summon adds, spam balls and then disappear again, repeat forever.

Wiki says he gains spirit charges and heals per charge on their expiration. But i don't remember it being a problem.

I think it was bugged then, because he gains spirit charges from his summoned adds, and he kept summoning adds and doing spirit burst, so he kept healing. I killed all of his adds, so i have no idea how he actually gains spirit charges.

But anyway, the problem really is that he seemed like he was stuck in a loop. It was probably less than ten seconds now that i think about it, but def around 10 sec, inbetween each add summon phase and him healing from spirit burst.

Accoridng to the wiki it looks like i'm not supposed to kill the adds? I am so confused about a boss i've probably done more than any other boss in the game, except conquerers.
