I think using sacred as one of the requirement of new quest is a good idea. Change the duration of PvP ladder to 2 weeks. We have too many pvp tokens in the market. Doesn't need more to deappreciate the price.
One of the option. Buff sacred wing. Adding a slot to it is good.
Bout the involvement of newbies in PvP room. Could try something like. Week 1 of the month open up the Kingslayer PvP room, week 2 only enable the Excalibur PvP room. So newbies have higher chance of winning during week 2.
