I dunno, can be called anything that fits the current "tank role formula." Give them:
A short-duration strong mit (insert skill name here)
Rampart
A 40% mit with some funny additional effect (insert skill name here)
A party-wide mit (insert skill name here)
And of course your 123 combos plus a 60-sec burst combo.
Done.
As for the job's name and what it looks like, why bother?
