In MMOs, I usually pair up with a partially-sighted friend.

When it comes to FC membership, this has been a mixed experience for her over various games. Often, groups are intolerant of her perceived 'weakness' and unwilling to give her the time to focus and get her bearings in group content and raids and so on. Someone with a vision-impairment that comes and goes intermittently can often jeopardise that... so negative attitudes are kindasorta understandable... but it means that we are both pretty choosy when it comes to which FC we join. The fit has to be right. This is why we often form such things ourselves.

So... when it comes to FC invites... please try and bear in mind that players come from all manner of backgrounds and have all manner of requirements that may not be bog-standard or obvious... and that it's infinitely better to talk to and approach people rather than spam the invite continually.
