I don't know what's up with this no brd getting invites deal. Every shout I ever see includes BRD in it for procs. /BRD isn't THAT popular.
But even then many people who do the shouting probably already have a brd. I've actually never gone to a pickup group and not seen a brd whether it was someone else or myself. I've never seen a blm/brd. But then I haven't joined many pick ups because I don't really need to.
Any LS that does Abyssea has enough brains to have a BRD and COR around. If they don't have one or the other or neither, they sure enough wished they did have those jobs as mains. You are gimp without them plain and simple. The answer to this so called problem is to start being social, join linkshells, and enjoy this MMO as it's meant to be played. And the same holds true for the other jobs. A dedicated LS will have all procs covered at all times. The only jobs that are left out of the 18 man alliance mix is DNC and SCH. I mean I might be wrong on this but I remember doing the math and it came out to like 16 or 17 must have jobs to cover all procs and there was room for 1-2 more, which probably would fit another WHM or 2 long before other jobs. Or maybe it was like 14 or 15 and I counted the extra WHMs for 16-17. Anyways.
People have been going on for awhile now about how broke Abyssea is, and really the problem isn't the procs. It's players not wanting to team up as a linkshell to take care of business. They want to do pick ups so they don't have to join a LS and make an obligation to play and that's all fine and dandy. But it doesn't mean Abyssea is broken. It's working as intended. It's just "broken" for pick up groups.
