Alright, so I released a poll asking some questions regarding KitPvP updates (
http://minevast.com/poll ) and it looks like there's going to be a fresh economy restart, including some other updates. I wasn't sure if I was going to reset gems or not, but in case I didn't, I disabled converting them to prevent people from transferring their currency to the new economy. ( Gems will most likely reset though ).
Also Blades will be replaced with the old group called "Warrior". We're also most likely renaming/updating all the kits and getting rid of the "race" idea. More information will be out for this soon, you can see a sneak peak of some features to come though on the Poll.
