The problem is there is attenuation so your buff for double exp then makes you play even less time. So you spend 10 mins per hour to get attenuated and now have nothing else to do in the game. Waiting for 50 mins between adventuring sounds really like an unfun game. Now if they just want to slow us down to start off the new content they could make it time bound. So we start with say 10% of our current skills then every day gain 2% automatically back. Then in 10 days you have 30% of you total skills back and so on until you are back to full power after a couple months. That way you still start at the lower level but you don't have to actually spend gold to get back your skills you just play and they come back over the time one would normally clear the content of ep2.
