As COR, I usually tell the BRD I don't mind pulling because I know how annoying it can be to have to pull every single meripo. Plus, I don't mind doing it every once in awhile. COR pulling isn't bad since our damage contribution isn't huge anyway, and rolls don't have to be recast as often as songs do. Ideally the BRD would probably pull and the COR would contribute DD, but endless chains are certainly doable with COR pulling and BRD healing/sleeping/buffing. Plus, in an all SAM /SAM party a backup healer is actually useful on occasion.
Long story short, if you really don't want to pull on BRD you can probably make the COR do it. We are basically reliant on you to get merits (well, if we want to get good merits anyway).
I've no idea if you parse much but I parse almost all of my merit parties and as a result I wouldn't agree a cor's damage contribution can be discarded to give the bard a break from pulling. Cor will be less than all the other DD's but the lowest DD in the party won't be too far ahead of the Cor if he's good. I am referring mainly to pick up groups so if you're one of the people who only merits with your LS then our mileage may be different I guess.
i just hit 75 brd last month. on brd i sub whm and as such i back up cure pretty effectively as a 75 brd. i also constantly keep songs up and do complex song mixes. i use finale like water w/o having to be told. why is me not pulling on brd an issue. i do all but 1 thing as a brd. last i checkd the people i party with dont send me money orders to pay for ff11. i make it clear i dont pull and people still give me grief over it
Bard pulls in merit parties because it's what they get invited for and it's what they're best at. All you can really do is put in your search comment that you will only merit if there is another bard in the party, then hope he doesn't leave before you do and is happy to do all the running about while you leech.
You seem to want it both ways, bards have a fast invite rate to parties because not enough people want to level the job (usually because of pulling) so they level a DD and accept slow invite rates, you seem to be happy to take the fast invite without doing the very thing you get that fast invite for. Bards generally have an easy time in this game due to the huge popularity of the job, you won't get chewed out for having sub par gear like a DD or tank would. You won't get chewed out for letting buffs drop like a healer would and you won't get chewed out for having a bad attitude most of the time, I've known quite a few who've had a terrible attitude "because they can". The most important thing you're expected to do is pull and if you're not prepared to do that then people will get annoyed and quite rightly so.
