Do the questline, it gets you a title and it only takes like 20 minutes tops. ("of the Iron Vanguard")
It's tempting to use since my paladin's name is End.. so.. End of the Iron Vanguard. However, Mistwalker is the only swag title that should be rocked now~
UBRS is kind of a cluster fuck, healing is a back to actually being tough-like it was back in the beginning of cata heroics imo. It's also pretty gay that it's entirely based off personal loot... all the bosses don't have a loot table for holy paladins apparently
