Only thing I can think of, regarding my situation and the fact that people who are more active (raiding and end game stuff) getting shafted to a sub-guild is to make the seperate guilds a bit more focused in intent.
ie. The heavy raiders could be in one, with an emphisis on habitual PVE/PVP raids/end game stuff, with an agreed log in frequency (once a month/week/whatever). This way the calendar could be specific to the guild too, making things a bit easier for all.
The other end of the scale (ie. Me
) could be in a slightly more casual sub-guild, with a more relaxed log in frequency, more new players/levelling alts to group up with, and some lower tier raids/dungeons being organized with us part timers in mind (Im lvl 75 and never even seen Onyxia, honestly).
With a PCG-wide chat, and the ability to make extra-guild groups for events, I can see this working a treat. It does kind of fragment the players, but given we all have levelling alts (even me), and most of us are aiming to get to that lvl 80 full-epic-raid-set end game, we would have something to aim for too.
Again, if this is all bollocks, just say, I know nothing about guilds and member caps, etc. Im just thinking outside the box.
