Not exactly too keen on wiping the squad cuz a DPS feels uncomfortable.

The wipe resets your cooldowns and requires at most a minute's run. Compare that to taking an extra 3 minutes to get to the end of the hall in the first place because three times the uptime was required to kill the enemies in three parts rather than all at once, effectively dividing your damage at any given moment by a third.

Trying a full pull once, even in the shortest of dungeons, will be worth your while.
