This is more or less the reason why I just leveled PLD to go alongside WAR. In something like Coil, I can bring either job and get the loot I want for both classes. I bought Darklight and got gear for both classes. I can spend myth on accessories for both jobs, but I have to prioritize when it comes to armor. Why would I ever want to subject myself to the unfortunate grind of leveling a DPS or healer and having to farm all that philosophy and myth and deal with a weekly lockout timer on Coil that makes gearing jobs with incompatible gearsets a losing prospect? I'm all for leveling jobs of different types to help out friends, FC, and LSs, but the current system doesn't really make it feasible. I guess we'll have to see what Monday's hotfix changes in regards at least to phil / myth tomes.
