While I totally understand wanting to play your preferred class in every situation, it's just not practical to expect this for every event/raid/primal/NM. In order to have dynamic battles, and raids, you will always get a 'preferred setup' for each different situation...the trick is 1.making sure every job and class has it's own content to shine in. and 2. making sure that content is still clearable by mixed 'less-optimal' groups.

This being said: SE designed a game that you can basically swap out classes/jobs on the fly. It's part of the games design. They sort of expect you to have mastered more than one class for 'Hardcore' Elite content. So basically, SE is rewarding people for being able to be flexible and play different roles on the same raid OR know how to stack a party pre-entry to optimize their time. I know it's not what people want to hear, but speed/5 chest runs weren't designed to be easy to get with every setup.

Also, while it's hard to judge the games direction based on only the handful of 'Elite' content we've had atm, as long as SE creates battles that take out Ranged Damage for example, or add in mobs with high magic resistance, Monk and LNC will get some limelight. It's just now, especially for 'PUG' groups, it's easier and less-risky to recruit certain setups.

Basically, if you want to try Monk in a situation where people don't typically use them, run it with friends first. Make sure you can rock it out. If you can rock it out, video it and put it where people can see. So often people don't think for themselves and do things the way others do it because it's proven.

It's PLD than needs serious love...they aren't even invited to tank....and are supposedly by description, the only tanking class in the game. It's like not letting WHM's be the main healers....
