Yeah, I wouldn't pitch a fit if I got into a group with someone in i90 or lower so long as we could clear the run, whether that be through me adapting to the needs of the party(acting as a pseudo tank as SAM or NIN for instance when we got a tank that was far below me in gear) or something else. So long as we get it done, that's what matters.
NOW if they're being an active detriment, unable to keep people alive etc, then I'd be a tad miffed. Otherwise, I'd just stress the importance of getting better gear than go on my merry way.
