DTV was actually pretty reasonable with full income/exp.
You just need to limit it to the right kind of maps, as in its current form it is actually very hard, and requires good gear.
With 1/3rd exp/gold, there isn't any reason to do DTV other than for funsies, as you lose more money and gain less than on regular servers, generally speaking.
Since it's only fun for the hell of it when your tired of other modes, and you're penalized for playing it, why the hell would anyone want to play DTV?
Edit: one possibility would be change it back to full exp/gold, then limit DTV with river/plains/mountainous maps with no buildings/trees, and make the NPC's a little easier.
A giant melee might be a lot more fun than camping, and harder to keep going for many rounds at a time.
PS. making the rounds shorter but harder to win would be nice.
