Commendation System: So who get's your vote?

[lackofwords]

I'm pretty sure someone mentioned this already, but it seems odd that you can not commend someone that leaves the instance before you even get a chance to open the commendation window. Even if you have commendation window open with their name there, it would be grayed out, so you can't select them. (unless if I'm remembering it wrong...)

Aside from that, the way I commend is more or less random
-Commend someone that actually did an awesome job that is way out of the normal scope of things, or have saved the fight from total failure.
-Commend a DPS that actually bothered to use their LB at all during any point of the DF dungeon
-Commend a random DPS
-Lastly, quickly and randomly commend someone that hasn't already left the instance, which usually in PvP everyone leaves before I can even open up the commendation window
