More on this idea:
- obligatory quests for all classes at levels 10 and 20 with rewards such as +1 class-specific stat for completion of each;
- Or a more noob-friendly version of obligatory quests at levels 25,26,27,28,29 (can be done in groups maybe);
It could also be an entire new class entirely quest-dependant. All 30 levels would be attained by completing 30 quests on top of XP. And maybe it could only equip items obtained by questing, nothing else. And every skill and spell would also be quested for. It would send the player running through the entire world.
