Suggestions:
-Nexon cash should be available easier
-A better server managemanet (nothing against you xD)
-Every Sunday at 18.00 a fixed and pre-set event (announcements).
-Every Saturday another fixed event at 18.00
e.g. Morphing into mushrooms and having a race from Lith Harbor to Ellinia.
-Morphing tools for turning into a Balrog e.g.
-A beamer with whom you can beam yourself to another town for little money.
-Beaming to bosses should be available to.
-To make this more attractive:
Free things for e.g. lvl 120 (you've to play some time before reaching that level...)
All for now.
