Terminology. Why does it bug me and others?

Don't be hatin'! This toon's alt is 15 gladiator and I'm thinking of rerolling pally because I've heard warriors struggle with threat (but their dps is better than pally I think?). I might be too lazy though and maybe I'll just end up taking the lvl 22 taunt spell from gladiator instead. (assuming my guild is gonna find warriors acceptable to tank in raids)
