First world problem xD

Depends on how hardcore the FC is, take into consideration the time people play the game, they don't want to waste it on people who aren't in the same tier as them Skill/Gear wise, or play/raid in different timezones. So filtering out the casual's from the hardcore is imho the major point of having this process.

There are plenty of FC's that don't require you to fill out anything, but what can you expect to gain from simply being in giant chatroom with FC buffs.
