I think taking away the kits is a major bump, and I also don't get why only mvp+ can mine those spawners? And taking commands away? please explain a bit more about the mojang rules and so on
Here's a couple suggestions for factions I think you should take a look at. Disable wither mob grief People glitch in those wither skulls, and I agree with how this is a big way to basically raid any base. I'm still neutral, just thought you should take a look. (Credit to @Mega_ ) Custom enchants This one would probably be a pain to implement/possibly have issues that come along, but is a pretty cool idea from over a year ago. Could possibly be on opfactions instead. (Credit to @Bantz ) My idea: Please claim the spawn area with the SafeZone faction to prevent users from claiming the area with their faction. Issues come from it such as inappropriate faction names.
They really need to enable hoppers, add more spawners, stackable lava bullets/water and add faction chat back.
In my opinion there is legit no point of resetting the first kitpvp if you guys are just going to make a second one. But still :D
