Here are my suggestions:
1. Make the trash battles less boring. Add more Elite types WITH NEATO GRAPHICS (i.e. Diablo Arcane beams); add legendary drops.
2. Add an auction house with safeguards.
3. Add chests to the "level" gameplay.
4. Add more of a variety of bosses to "level" gameplay.
5. Penalize death by using a "WOW style spirit res" where you have to hunt for your corpse.
These five ideas will go a long way!
