However l2jfrozen can be removed from this "formula", how? Everyone know about aCis (their refactor, rework, etc.) OK. You can take aCis as base and you can customize it, you don't need many hours to add all customs from frozen to aCis. So you will use something stable for for both types of servers (high & low rate). But if you want to reverse -to refactor, rework l2jfrozen.. hehe you need a lot of time. Would be good to end this discussion. So who won? aCis I guess.
