Okay... you're really making me sit and scratch my head trying to figure you out (which is hard because I'm totally exhausted right now). Clearly most people like you and appreciate your efforts.
Why is it so terrible that once in a while, you don't get points? Try to ask yourself that and give it some thought. Maybe it'll make you feel better.
Because like I said before, I always do my best and there're plenty of runs in which I get zero commendations. It bothers me a little, I guess, but in the end of the day commendations really don't mean much of anything. It's kinda nice knowing people took the time to give me a point and noticed my efforts, but it isn't the end of the world when I remember that through my efforts I still made the run enjoyable for myself and others. The points don't actually do anything, they're just kinda fun to collect.
The game is about having a fun experience within the dungeons, raids, whatever; not just collecting the points. They're only part of the overall experience. ;3
