I have always been using 1.7 on imperial and today I was unable to connect to any server using 1.7 I would just lag out. I did /helpop and the staff member told me that the server requires 1.8 and up. I used this server for months to build bases for HCF. Pretty much all HCF servers are 1.7 because 1.7 is the best for pvp. I have been using 1.7 the whole time with no issues at all. I don't want to be forced to use 1.8 Me and a few of my friends always use 1.7 on the server.
