I still have mixed feelings about playing as Random (random race). Although I enjoy the variety, it is difficult to improve at any particular aspect, especially since I only play a few games a week.
If I had to choose one race for this season, I might lean towards playing Zerg (gasp!).
How I'm playing them is fairly active, which is fun to play and cast, and whenever I win I feel like it's an accomplishment.
Of course, maybe that says something about the underdog mentality of many Zerg players ;-)
