Hyrist I dunno what game you're playing but, in real FFXI the only content you bring RDM's to currently is outside, and it's called voidwatch.
Really? Then I must have imagined the entire time in Dynamis, Abyssea, Missions, WoE's, Campaigns, etc.

Not everyone has the absolute best jobs available to them for all the content they play.
Not everyone WANTS TO BRING the best jobs available for the content they play.

I think it's you who's playing in the more closed community. Restricted entirely to the most dedicated endgame players who exclude any tactic but the one most approved by said closed community.

Voidwatch is not the sum of FFXI, nor is it the only thing RDM is 'invited' for.

MOST players actually play the jobs they want to play for the content they go to, not the jobs they are told to.
