I suggest that the exp event should be either permanent or no exp event at all.

As far as I understand the bots zylon is an x3 exp server with for example 3*25=75 and 3*50=150. Double this during double exp event.

On a nostalgia server like bots zylon 2008 it's better to just let people grind whenever they feel like

To clarify, nostalgia is part of spontaneity which is why it's important to let people grind whenever they feel like.

what times are the exp event nowadays?
