I think MvPs spawn rate shouldn't change. Or at least, leave MvPs spawn rate as them are in the Official Server. There are MvPs rooms, so, except for some MvPs, is easy get cards and drops. And there are also Bloody Branches, that spawn almost every MvP.
Actually, you get 30 cash points when you log in with your char. But if before you get 20 cash points everyday, now you have just the 30 cash points you get the first time you log in. Not sure how to get cash points except of donation, but I hope you'll gain by voting server or, just as before, everyday you log in.
Anyway, welcome =3
