There's a couple of ways to work on the Doom part of that fight. First, the boss is stunnable. A clever tank or a DPS with good reflexes can stop Mortal Ray if they're on top of things. Second, the cleanse tiles are just on timers; If he's prepping Mortal Ray just run to the next tile in the sequence and 99% of the time you'll either be cleansed instantly or after a second or five of waiting.
The biggest issue with that fight is that things can get hectic fast due to the mechanics involved. OH NO, MORTAL RAY IS DEATH. OH, ALSO BEES GIB TANKS WITH STING. OH GOD, THE CLEAVES. No part of those is particularly challenging on its own, but put it all together and it's orchestrated chaos.
