Two things I enjoy :
1. Leveling up to about level 8. I like the shorter quests and I find them nicely balanced with regards to length, traps, mobs and bosses.
2. Finding a chilled out, friendly PUG not obsessed with Bravery Bonuses (What a pointless, divisive mechanic that only serves to polarize a player base that is too small to survive much polarization.) and just wanting to have some fun.
