man , this is unfair !! while you can only use a maximum credits by day , and only can buy credits in sets (50-100-200 ...) there will be balances in the realms you are playing !! those credits should be available for the User wherever he is playing , not for the realm he is playing !! that is a serious upgrade that should be applied to players !!
i understand your situation, i used to think the same thing ,but then i realized that if it was possible to transfer credits between realms players would hack other players accounts and then steal all their credits
transferring credits between accounts will somehow cause a promotion of cheating
