You have very well said that you're on the custom made shard side so if you are supporting custom then you will be helping the shard to break the rule when they claim that it's OSI clone.
This is MB
Fun side - Only the rich can do spawn, get power scrolls, and only made for large guild.
Bad side - Poor player cannot do spawn, can't get power scrools, and can't even do spawn even in small guild.
This is Opywang
Fun side - All player rich, and poor can do spawn, get power scrolls. and can evade raid.
Bad side - Large guild will have to scout more, work harder to prevent players from getting PS.
What's even funny that how OSI fix it like that. They balance it for both the powerful, and the weak. You wanted to make it where the weak can't have any access to it so that the only person can have it are the powerful.
This right here is pure exploit it's made for the rich, and the powerful while the poor can't enjoy the game, and have fun. So the only person having fun right now is the Rich, and the powerful in a large guild. While the smaller poorer guild are suffering.
This is a selfish acts the only fun thing about this is power, control, and monopoly. The reason you're refusing to make it an osi clone is for a selfish reason. It's selfish it's not fun at all it may be fun to you, and to you only, but to the rest it's no fun.
