In Thailand, there's a game name ECO(Emil Chronicle Online) opened about 5 years ago. In it's first open beta, the maximum exp for level up is *100 of beta server and original game from Korea and Japan (means you have to grind 100 times harder for a level) resulted in almost 80% of all players quit in 3 months and the company have to adjust the EXP rate to normal after that but it cannot bring back what have already lost.
I don't want to see this game repeat the history since this is closed beta it can still be fixed and adjust to an acceptable rate. Staffs please reconsider this issue.
