@Blade you needn't be so strict with your raid lineup, there are plenty of players who would like to play and no doubt some of your teammates want to mix it up a bit, play with others, different play styles etc.. Or even they want to beat HM and know that starting on a Sunday isn't the best way to do that.
If you're ever down a member I'll happily join you on a Sunday, even if I've beaten it already, if people need a hand getting to 32 or beating HM.
If I remember rightly, you and Kav were there on our first ever VoG run. I've raided with all of your teammates at one point, as well as most of the other active clan members, it's more fun playing with everyone. New clan members like @DaveTheCow are always looking for a space, that's why whenever I start a Raid I try to have it "Me and <space>, <space> etc.." rather than "Me and @mention @mention..."
