Although I agree other server's should have resets before KitPVP does, there should be separate threads for those. This one is aimed at Kit.
A reset would do almost nothing to the diamond people, so that shouldn't be a reason for a reset. You'll see them come back within day. Next reset, it would be nice to see something to lessen the power of diamond armor- or make the normal kits stronger. I realize it's not that difficult to kill one diamond player, but it's almost always a team of players rather than one.
Mentioned above was something about not having enchants. I would agree with something like this, maybe something like only allowing diamond to have a certain protection on it, so there's not teams of 5 with P4 U3 [insert 10 other custom enchants]. If not armor, swords are extremely powerful. They aren't bad without custom enchants, but it's pretty annoying when you get blinded/slowed/etc etc etc.
