I think you won't face much hardships in this quest. But the boss is Stun-immune, so probably CGR would be a reliable choice, considering he has great BP, and he's also Incinerate immune.
Honestly the path to the boss is more difficult than the boss itself. Nullifiers work great because the Regen path makes the defender unblockable with Regen Buffs and if you can prevent those it's definitely going to help.
Sentinel is just a test of endurance, just keep in mind that you won't be able to trigger Buffs for some time (20secs or more?) after you start the fight.
