[Useless]

I know this is most likely a stupid idea (viewed from staff side), but i wanna throw it in anyway: Hand out skill orbs (or whatever) triggering a 24h/48h Skill boost, meaning that the increased skill gains start from the moment on they use the item. That way you are not depending on the weekend, also you can easily repeat the event. I know the point of the weekend skillboost is to get playerbase up during that time to lure new players and it will most likely work that way, but only on short term. What you might wanna think about is some sort of playtime rewards to keep them here, especially if its something they cant just buy like skillgains. Ie. after a week of gametime you get something like a 12h Skillboost, after 2 weeks you get something different, after a month like a 24h skillboost and so on.
However personally, even if I know I wont be able to use the skillboost next weekend myself much aswell, I appreciate your effords and thank you for it.
