Earth and Beyond developped an xp system where you can gain :
- Combat XP, well, just by killing stuff around.
- Trade XP, by selling with profits items to vendors / players or doing tradeskills.
- Exploration XP, just by discovering check points in zones that you never visited before.
I was very supportive of something along these lines a few months ago, and now know that it's really something fun that let you develop your character XP-wise, while you're having fun, not doing over and over the same repititive thing.
I keep up my suggestions for AO :
- Let Adventurers get some XP the first time they discover some places.
- Let Engineers get significative XP when creating stuff.
- Let Fixers get significative XP when hacking stuff or pick-locking doors and chests.
- Let Crats get XP when saying "Your call is very important to us, please hold on the line" if their team request some urgent mezzing.
