Well I normally don't have a problem using channels/lfm panel to fill groups..but for this it really seems more time efficient to balance the group in advance. It sucks to spend over an hour looking for the "right" group of people.
Saturday, Feb 25th at 10pm eastern time, here are my spots open:
main tank - open
off tank - Ismashed
healer - judo
2nd healer - Tenauch
caster - open
kiter - open
light monk - dolomight
artificer - phrida
bard - open
DPS - wrunt
DPS - cryo
DPS - open
...because there are very "few" dps spots, I will be stingy on who gets them - and people who have been tanking/healing my runs in the past have priority in those spots. (by DPS spot, I mean people who's only job in the group is simply damage - light monk arty and bard will probably be doing dps as well, but they have other functions we need.)
I have a bunch of characters off timer and can adjust who I bring accordingly, I am planning on my favored soul for now.
