You have to do a minor hunt to find out what M&S stands for on the Greedy Goblin's blog. I'll save you the trouble, M&S stands for Morons and Slackers.
Another coincidence. Not too long I mentioned our guild was going to lose members for reasons similar to what this blogger mentioned. You can read it in full here, but I've copy-n-pasted the part I want to focus on here:
The...reason for gquit is "guild does not progress fast enough", meaning "M&S is pulling me back". This case I suggest you to fight for your progress. You will mostly lose and have to leave. However I suggest that if the M&S make you leave, give them hell before you do! The reasons:
* I assume the guild is not an M&S ghetto (the fact that you are still there suggest that). I guess Tobold's guild is good example: can clear Naxx, can't clear Maly. There must be some good players, several average guys pulling their own weight and some M&S. You are not the only one who want progress here! However they are social, meaning "won't speak up if it can cause confrontation". But if you speak up, they will join. So if you start openly speak about X or Y underperforming in the raid, several will support you. (Always target certain M&S, blurry comments offend those who are not targeted and ignored by the targets.) Result: most probably several gquits on the M&S part or you being kicked.
* People overvalue their groupmembers and the group. There are masses of scientific research proving it. So if you quit quietly, you'll be the "bad one" while the group will be the "victim of treachery". They will most probably think that you were a loot whore or a lazy prick who did not want to work for the group. No one can claim that if you are kicked after attacking an M&S named X or forced to leave by everyone supporting him (he does 700DPS because he is just ilvl200, needs more gear). Everyone will know that you wanted progress and blamed not the whole group just one-two bad eggs.
* The grass is not always greener on the other side. The other guild you join may be just as bad as the old one. Or worse. You will have thoughts that "after all they were not all that bad". And you crawl back, keep on boosting M&S and lose all right to speak up. After all you knew exactly what kind of guild it was and came back. If you burn every bridges leading back to such guilds you will have to move forward and finally will reach a proper place.
* Even if you lose, you made an example that speaking up against the M&S is possible. Most social people believe that criticizing others is simply evil and the whole world will hate them. They will see that you are not hated by the whole world, just by the M&S themselves and by their close buddies. Maybe they will not follow you instantly. But when they see you as Twilight Vanquisher while they are still wiping at Thaddeus, they will remember that it all started when you told: "I won't suffer these M&S anymore!"
PS: Don't bother to go to the officers. They are there, they could see the obvious with their own eyes if they wanted to. The pure existence of M&S in the guild is an unquestionable sign of their failure. They are either M&S themselves or socials who rather boost M&S than risk confrontation.They will most probably claim that the M&S is just ungeared.
Now what GG said is a bit harsh, but the PS is what I'm faced with currently. I realized our guild leadership is okay with status quo and no matter how much they say they care about progression and beating the best of the content, their actions prove it is not a priority.
Our guild has very few or zero raid members who are undergeared now. Kel'Thuzad continue to stash some of the best items in the game currently under his billowing robe, so we have that crumb of cheese propelling us through the Naxx maze. But we could also burrow right now and not emerge until Ulduar is released and perform almost exactly as we would with a few more axes and maces.
So instead of attempting speed runs our guild goes through the motions and some of us die inside.
On a good note, I'm coming to terms with my guilds lack of determination. I've decided to become an S, but how much of an M does that make me?
