Tiny, I think the filtering check boxes need finer tweaking.
There should be a way to select multiple wanted classes.
Lets say we need 1 monk healer, 1 rogue, and 1 guardian druid.
Right now there is no way to filter just to those, attempting to do so would enable druids of all specs to wait list.
The way it is setup now probably would help filter once you're almost full and need just one more person.
One last thing, are you going to release something similar to my idea for the find premade tab ?
For the Find Premade Tab:
The newest version would simply include a new checkmark box, next to the send beer and qualified checkbox. This checkbox could be called: "Wanted"
When a user check marks the "Wanted" box it removes any premade from view where their role isn't needed.
