The game is each time more foccused in the high end content, all the dungeons and updates are only for high level with powerful gear players... So a increase permanently the exp, kung fu, drop on weekdays to x2 and on weekends (just saturday and sunday, your weekends are too long) to x3. Why would you do that you might ask... Since gold is useless to buy highend stuff (yeah everyone asks for absurds amounts when it is not CC) f2p gamers have to farm more to buy CC from others or to craft the items we want ourselves or even get some rare drops to trade for. This would also fix the economy problem a bit, with more goods in the market their prices would lower quite a bit.
