Depends, in my guild there is very little required so in turn a very relaxed atmosphere. And We like it that way, no fuss, no muss. We ask that if you join tw you at least place a defense but it's not mandatory. For the tbs it's just at least dump your gp if you're not really into it and we're cool. For the raids only about 35 to 40 of us do the hstr, the pit is on sim and the tank usually only about 15 to 20 participate.
So, if you're in an extremely active and competitive guild, my guild would seem like it's inactive or has low participation. But it's all in what you want from your guild. Currently we have 44 members and for this tw only 35 have signed up. And I have posted before in the guild recruitment section before to no avail. But it's all good since all content is available and doable for us.
Some folks are looking for certain things in guilds like orginization, structure, leadership, 3rd party app useage, how well they do in tw and tb, how often and fast the raids go down etc.
Good luck and game on!
