My guild finally killed him last night. It is kinda a hard fight due to tight dps requirement of around 40.3k. We had him enraged a lot of times even without any death. I will give step by step instruction on mechanics on how we killed him.
Our main issues were tanks getting killed by RNG crits and lack of DPS. 11/11 HK would not even be able to kill Ituziel. I would advise to try killing Matron WITHOUT using any tomes before you attempt this boss.
