I may be a little spoiled from WoW, but I just don't have the patience to target a mob, right-click my portrait, choose target icon, click target icon, ...Whew, now that that one is done I got 3 more >.<
I would really LOVE to be able to bind the target icons to a key.
Click mob, press button, click next mob, press button, etc.
Not only would it make it a lot faster to mark, but people may start marking again and I won't have to heal 3 people at once.
Am I the only one wanting this feature?
