The thing about that list is that Sheltron is so good for 50 raiding, you should count it twice.

Tank DPS matters less in 50 MINE. Potency creep on the DPS jobs makes bringing a lower DPS tank with superior mits a much more attractive option. The content still puts out more damage relative to max HP than any other tier, and importantly, the shape of the damage is different. Holmgang is well-suited for soaking TBs in the current 'giant overmax hit followed by nothing for 5 seconds while your healers pump you back up' design meta, but Coils is often heavy damage phases with crit-enabled autoattacks mixed in -- for example, split-tanking in T1 or T10, I can just use invuln on PLD or DRK and the healers can almost ignore me, but if I tried the same on WAR, I would likely die without a last-second Benediction. If a WHM isn't present I might as well not Holmgang at all because the healers are going to have to pocket me either way. And having to heal your tank more often is huge in content where heals actually cost 1000MP.

Even DRK's Dark Mind finds more use in Coils than warrior's -empty mitigation slot-.
