I think it's a good idea. I leveled up my CNJ during phase 4 to 20 using exclusively groups from my linkshells (Intermission, Corvus) so that the RPC folks playing DPS didn't have to wait in line for half an hour or more just to finish each step of the story quests. I think I ran the chain of three dungeons three separate times on Saturday to help folks out while gaining a few levels myself.
It also helps build the community. Even if a player isn't the best DPS, tank, or healer you've played with, in this kind of environment, there's incentive to work with them. Offer helpful advice and such, because unlike a random pickup group, you will likely be seeing that player again, so you'll invest some effort. If you help those other players out, there's a high chance you'll play with them again and have a good time. I think it helps foster community while improving the gameplay of that community, in this case, the RPC community.
