RFB can't be compared with a private due to costs which some players have paid and others have received almost for free the same possibilities.
Over the years we were the ones who paid amounts to craft for example Opaniels armors and weapons and now it's full Exchange Market with them obtained for free.
I see the number of players bigger than before only during the hours when the Power Arena is held then the maps are just as empty.
We sent a lot of opinions over which you have gone without taking them into account (not even some new costumes).
About the armor called Onyx I already sent a ticket in which I have specified as it is Transcended would need some changes to balance a little, implementation at set effect 15/20% PvP Defense it would rehabilitate things.
