It can be somewhat interesting to see how people lay things out. However, I think the only way you can really get valuable information on what works for another person is if there's an explanation to accompany said picture. Information about controls, typically spot in raid (MT cleric, OT cleric, Dps group? all 3? maybe just OT/DPS?) i would think have a strong influence on how your hot bars and windows are organized.
Neat looking there =)
well i suppose it isnt interesting like Aditu said
which is true but some folks like to see, maybe
it'll even convert them in to using a diffrent ui
for other characters they play.
