Have you been upgrading your gear often? buying ship gear? upgrading cargo hold and inventory slots, learning mounts and buying mounts?
cause all in all...its been pretty tight. granted i'm not 40 yet. i'm an alt-aholic.
lvl 30, 24, 18, and two 12's.
Overall i find money gets tighter and tighter as i get closer to 30. managable so far...but it looks like skills go up in price too much to fast!
