Hi,
I have more than two friends playing as a tank and two friends with whom we can play only on weekend.
So, in regards of the tank friends, every week we have to turn one down from joining Coil runs.
And in regards to people playing mostly on weekends, the rest of our group is supposed to do what? Either get our Coil clear during week or sit around doing nothing waiting for the weekend?

Was it so hard to introduce tokens for each Turn clear you can get only once a week, but you can enter the battle as many times as you want with as many different friends as you wish?
So much for encouraging us to build up a community... As of now, we're pigeon-holed into 9-man clicques composed of exactly 2 tanks, 2 healers and 4 DPS. :/ And don't give me 'just change job' - 300 tomes of Mythology per week prevents any such ideas even IF I fancied playing something else.
