Laziness to quote.

Red Mage can be put in, but I personally can't see it myself as a tank but not going to say it's impossible.

If you all remember, this gear is typically shared throughout the jobs save your JSE. Red Mage, is light clothing. They CAN turn this around and make them wear bulkier gear, but that would take away from what Red Mage is, right? A small detail at best. I can't say anything on abilities because there are such things as JSA, so this literally can go anywhere. As long as RDM is given a 1-2-3 for Enmity Combos, they can hold hate. Throw in some RDM oGCD stuff for DPS. Boom. Look. RDM can tank. This is how simple the style of the game is though.

Hybrids CAN work though. But it's not so IN YOUR FACE as most other games would have it. Examples? We have them in the game already, but people don't realize it. AST(Healer/Support), BRD(DPS/Support), WAR/DRK(DPS/Tank). They're there, but their definition is coded by 1 of 3 colors as well as how the game pushes them to be. HOWEVER, this game does not support someone who's nothing BUT support because it's going to leave a role short to carry out some content. Be it Healer(AST), or DPS(BRD for example if they were pure support anyway).
