Azure, Mei, Mabui and GNW TenTen would be destroyed by a team running Hashirama. Passive barriers are good unless you cannot stop a manual one.

My server actually has good diversity. We have Fire mains, Wind mains, Water mains and Lightning mains mostly. Earth main is pretty rare atm. It's funny how meta's get started though. I guess it truly depends on the environment of the server.
