I always try to give out commendations at the end of each match, if I am fast enough before the players rush to orbit. The player that catches my eye the first gets the drip commendation, then I go to the next screen and hand out the rest depending on who carried most, and joy usually goes to the funniest/coolest name. However if a player was a jerk or not carrying their weight such as being afk, I try to remember their name and withhold commendation. Also Trials was bugged last season and the one prior that you couldn't give any commendations at all. Typically at the end of the season I will have given about double what I received, which I feel is about right.
