»How to buy kit in Skywars ?

Hello, first of all I want to clarify that I am French so I use google translation.
Sorry if the translation will be bad.

I am an "old" GuildCraft player, I had to leave because the server was switching to 1.8.
I came back today and saw that in skywars you have to have a certain rank to buy the skywars server kits. Knowing that I had to buy all the kits before this reform I would like to know how one can get the kits.
Should we spend real money to get the "top ranking" so be able to buy the kits in skywars?
Thank you for your answer in advance.
Still sorry if my English is bad because I use a translator ^^
Good day, good bye.

 

Hey Asayda,

Kits in Skywars are bugged at the moment but we are trying to fix it as soon as possible.
