10 man is not natural.
I have maybe 3? people that I consider friends. And we don’t really play together.
I tried running a guild in TBC, and we didn’t get far. Just throwing in randoms doesn’t work.
Tried running a guild in ICC, didn’t get past Sindragosa in Normal ( then friends carried me through Lich King.)
10 man is not the natural group size, I don’t think there is one.
I can’t even find four other players to do push keys.
If you like 10 man so be it, but to pretend there’s no admin work involved, just isn’t realistic.
And if you care about actually progressing… that takes even more.
You can more easily eject 15 people from a 25 man guild, and be left with ten actual friends.
