Excuse me sir, but are you sure that you logged on l2energy and not any other server?
there is zero lags/delays and no bug was found until now.
However, the server is in beta phase so if you wanna report smthing, feel free to use our forum instead of posting invalid comments.
About donations:
First: they are similar on every mid rate you will see around and you are not forced to donate in order to play.
Second: donations will be opened at least few days after grand opening.
Edit: Beta phase is on, all players are welcome to enter in game and test everything they want.
