BLM posting about getting refreshed? If a taru BLM runs out of MB during a chain, he has issues. And a party with 2 BLM, they should need even less refresh. You shouldn't be complaining about not getting refreshed. I assume it is Reishu you are talking about about, and I have had the pleasure to party with her twice, and hopefully again in the future. She is a good RDM. Her enfeebles stick basically every time, refreshes when it is needed, heals when needed, and is all around a great player.
Refreshing 6 people is a hard task to do, especially when she has other jobs to do. Enfeebling is a main part of the job no matter what way you look at it. A WHM is busy curing the puller who usually takes a hit or two on the way back. A BLM should be rasping, frosting, whatever it is they do. At that point, the RDM is casting dia, paralyze, slow, and your other basic enfeebles, which in the end, conserves more MP that a refresh will ever give you. The refresh cycle consists of the RDM -> PLD if there is one -> WHM. That is the main cycle. A BLM shouldn't need refresh if doing their job. Nuke -> Rest -> Nuke -> Rest. The only BLM that needs a refresh is a chain nuker. Yes, most of the time you will get refreshed, but case in point, you shouldn't need it during a chain to 5. I would say a DRK needs a refresh before a BLM ever will because those absorb spells help out everyone, even the BLM with Absorb-Int. Before complaining about a RDM not doing her job, get your priorities straight and stop nuking like crazy.
