Yes when servers is empty and there is noone farming on low areas you can read lvl85 in like 5 days or something like that. But when server is fresh, There is no freaking chance to level up so fast.

Ofc if you got lots of real money you can donate those kama/laba passes, so you can reset cooldown for those and just farm lvls by them.

But with normal leveling without donate and 5k people on start zone there is no chance to get 85lvl on few days

Remember that everyone starts on talking island, And everyone going to do same quest line at start. Everyone got same 1st class change and 2nd class change too. So camping those quest mobs going to be pain on fresh server.
