Please let's not turn this again into the usual "Healers and tanks are the only important role, DPS is an inferior and less important role" argument.

Nice read OP, I'm thinking on starting to tank myself, but I don't really know whether I should go for PLD or WAR. Apparently WAR has an easier time to tank from lvl 1 to ~45, but then gets rejected a lot for endgame content. Is that true or?
