Its true, there are not many things to spend money on.
I can list a few though:
AoL's
Potions
Houses
Mounts
Runes may be available in a coming update. I have started working on the new area, Karlopos Island.
Karlopos Island will be for level 20+, and already contains 4 new monster types (including a boss), 5 new quests, 2 new outfit quests, 1 mount quest and many new items. There are 2 new NPC's so far and this is all contained on 3 small islands at the moment. The theme is beach monsters. There is still more to be added.
On other notes:
Monk's tri-kick now hits 3 squares around the monk (in the front).
Small map edits
Changed cooldowns for some spells, everything is looking nice now in my opinion.
