The old NLC could be coming back?

In theory it does. I guess it's just not common enough or it doesn't really work anymore.

We got:

1. Mounts (used to be a good meso sink until everyone and their mother got Flash Jump + easy teleports to anywhere).
2. Now Mastery Books (7m-17m to max a 4th job skill really adds up.)
3. Donations to NPCs for titles (guess it's more gimmicky than anything)
4. Evo World cores
5. Repairs for any durability items
6. Potion costs, especially if you class has no way to self-heal
7. Profession costs

I know I'm missing some, just can't recall them right now off the top of my head.

8. Job change. Dat 500 mil per change at level 200.

Unless 7. refers to job change. Because professions by themselves is no meso sink lol
