With regards to people not responding to guild invites -
- WoW has become World of Solocraft. Back in the old days, if you wanted epic gear, you had to raid. Now you can run dailies or PVP [it has resilience but it also has some very nice stats].
- I see maybe 2-3 people a day who aren't in a guild. Perhaps they are soloists and want nothing to do with being in a guild. Every guild seems to have "click" groups [those groups of people who sit at the same tables in high school] - I hate that type of environment and I see that type of attitude in a lot of guilds.
- A lot of people with unique guild names - I suspect these are soloists with guild banks.
- The rest already in established guilds who are happy where they are at.
I also think it's because there are too many guilds advertising now. I see at least 10 different guilds spamming trade chat everyday.
Alas - a lot of guilds have schedules which I honestly can't do - "guaranteed" sitting in front of the computer for 4-5 hours on any given night - weeknights or weekends. I have a frikken life - I'm not one of those guys who's unemployed without any responsibilities that can sit in front of the computer 20 hours a day.
3 hours max one night from 9pm-midnight PST on the weekend would be ideal - that's when the kids are snoozing and the wife is off playing facebook games.
What's really odd - and I've looked around - a lot of guilds want to start anywhere from 5pm-7pm "PST" no matter what server - PST, CST, EST. Alas - I made the mistake of joining up on an EST server a long time ago - so my "raiding" will probably be in a PUG when people are epic'd out and running the raids/dungeons for loot drops/crafting bops.
