The first 2-3 wins your Saint got in WonderKing PvP, and they were against another character of mine. But honestly, 2-3 test runs just to try out skills (WonderKing zed) would hardly be farming wins. Now, you just make a room and accept challengers. You have a bit of a win streak now, but that is because you are a Saint with a lot of practise surviving in the Hellen Office portal, so fighting the random Assassins and Beserkers that challenge you, which isn't too difficult
It is recently been brought to your attention that the amount of exp you gain is based on PVP rank. This means at higher ranks, unless you fight people with high ranks (which can essentially only be obtained by fighting similarly ranked players), the players will have had to earn their titles in fact, as you lose pvp exp when PVPing matches. By the way, you can enjoy the most secure WonderKing gold here.
