I feel cheated by the variable time limit. I like 12 minutes, but what i get is 6 or 7 minutes. This is a joke. In QL i am getting 10 minutes, period.
Another problem is what is happening after the match. I can only play like 3 matches against the same opponent. And the decision to leave is made outside of the map in a menu, enough time to think about not wanting a rematch. Compared to QL i seldomly getting a rematch. Also in QL i can just play my opponent as many times as i like. Also in QL i can see which people are on servers and playing. In DBT i wait for some magic to happen and i can’t estimate the likelihood of getting a game.
In Diabotical in the Play menu you can click on the Create Lobby button, set the visibility to public, set game mode to Duel Classic, select Duration: 10 minutes, start the game and wait for a player to join through the match list (this doesn't use or affect skill ratings).
