Just world top parses on this boss are done by frost mages and unholy dks padding on adds so they can rank, but it's absolutely not necessary for killing the boss. You don't want to nuke the crawgs. You want to keep them alive as a combo point machine for your 7 sub rogues (nowadays can be less but early progressions 6-7 was the norm). You want to nuke prio adds like crushers. DK could be useful to grip hexers but depending on setup you might just cc them and ignore them (lots of rogues = skipping another wave of hexers = just cc both spawns and recc at 40%, forget them).
Tbh in my guild our dps dk was just swapping to rogue alt on that boss because it's just so damn broken.
You might as well use your dk as blood as the 3rd tank, most guilds use a dh but that job can be done as dk, pala or monk as well, you just want to pick up crawgs and offtank them and kite them if you'd take too much damage (however when you take damage they heal, preventing them from dying too fast, and you don't want them to die too fast). For example one of the world top dps dks, Verrsdk is going blood on that fight. So no, you don't need a dps dk.
