I love the idea behind this, but I think this sort of events is only for a specific group of players.
Let's divide the Emps-World community into 3 groups: Skillers, Pvmers and PVPers. I personally don't like skilling at all, Pvming is okay for me but I don't enjoy it. So players who share my opinion are already left out for this event. Maybe we could come up with an event which attracts both three groups. Or maybe different sort of events (during winter one for skillers, during summer one for pvmers, during spring one for pvpers etc...)
So to summarize: I think this is a really great idea, but I think it won't attract all players or only a specific group of players.
