Don't be dismayed. There were plenty of times I went into LFG for raid groups, actively looking for a good one myself, where people posted they wanted "experienced people" with "good guns". There were lots I went with that put out that criteria but didn't live up to it themselves, so if we got into Crota or the VoG and people kept causing wipes, I'd start bitching loudly that there was no excuse for a raid taking over an hour and a half because I demanded efficiency out of a group that claimed they were good. Point of the story is, just because people post things like that, wanting those things, doesn't mean they fit that classification themselves; saw it plenty of times, in both pve and the crucible.
