People are quitting for the below reasons:
1. there is no way for those who don't mall to be on the same level as the mallers
2. have you seen the prices for the ring and necklace vouchers?
3. there is no way to get pet fruits ingame, rations, character aparels, demonic fruits for pet marriage
All of the above GM needs to consider not to mention the below.
There is no way for persons who don't have high level characters to obtain unique gems as CA is the only way to do so...The server game play is just piss poor and does not encourage PK maps of all levels, to get better clearly the only way is to mall to or make a high level character and hope to get you some gems in CA
