i don't care about rare costume if that costume don't give any permanent effect. I want something to recover the instances lost, exp lost in 4 days i've cant play. Just giving 25% extra of each is not enough. I was waiting something like Sunglasses  quest, or something nice for us, just giving extra exp is easy way.
Its not their fault having ddos attack. Dont blame them for your expi loss for the past few days. Just be thankful server is quite stable now. Geeeeeizzzzeee.
