Events like these are good for resting. Especially on DMM where there is such a huge player base, that you never go long looking for a RB.
All you have to do is hit RB of other people and run other maps.
Granted If you need Life Crystals or gold you can still run the event map, with all the discounts and bonus gold buff etc. But WS is the name of the game at least until they open the next part of the event.
