My current schedule has me working Sat/Sun so I have not been involved (at least much) with weekend raids.  I'm a bit curious...  Is the problem that not many guildies are joining these raids and you've had to fill in with PUGs including players which are too new, not very good or don't follow instructions very well?  I like the idea of weekend raids, the more raid days there are the more chance I'll be able to join up more often due to my changing schedule.  Plus, as you said, we have had several join our ranks due to these raids.  But if I'm understanding the situation correctly it sounds pretty painful with more PUG than guild.
