I personally hate OP servers. I know lots of people like them, but I would not like to see them added.
I Tried An OP Factions Server Once, Bedrock Bases Made It Awful. The Starter Kit Gives You 3 Stacks Of Bedrock :/
OP games have no challenge, nothing that can make a person want to play it to get a good advantage over others. If anyone could get let's say 100k in 10 minutes it wouldn't be very fun, would it? :/ Imo it wouldn't be that fun, but some people like those kind of servers. Personally, I don't like this idea and probably wouldn't play these much, but if these were to be added at all, I think some other, more requested games would be added first.
