Not really balance related, but some attention on this suggestion would be great:
DTV RatesPlaying DTV sure is less stressful than PVP servers, but there is no reason for the experience gain to be as low as it is now. Some days ago, we had a really good team with ~20 players on Istinar (small map with a lot of action, i.e. fast rounds). Afina stopped the round time from start to finish; I calculated average multipliers. Even on really high waves such as Saracens, multiplier did not exceed x1.8.
Think about new players who aren't very familiar with combat mechanics yet. They join DTV to practice blocking and gather gold their first couple of generations to get a few masterworks and improve their skills. If they are discouraged by low experience rates even with high waves on good maps with strong teammates, they are likely to quit before even entering competitive play on PVP servers.
Edit: With the skill level continuously climbing up (veterans keep getting better), the psychological barriers to enter PVP keep rising. DTV as a haven for new players could compensate it a little and prepare them.
Edit2: Are all people who are editing DTV stuff currently MIA, or have we got anyone?
