I know I have posted a suggestion similar to this before, but I'm posting another one that hopefully more people will agree on.

Minecraft Name: doodlecatt

Suggestion: My suggestion is to make a few arenas where kitters cannot use their kits. We will still have the same arenas where people can use their kits. The arenas where you can use kits will have better cash prizes than the arenas where kits aren't usable.

Reason: My reason is that it's really not fair to always lose to people just because they have their OP kits. It's much harder for us non donors to win in arenas that have a bunch of kitters. It's also very annoying when people use multiple kits in one game; making them even more OP. If you cannot go through with my suggestion then please at least make it so you can't use more than one kit in an arena.
And no, it's not that I suck at PvP. I sometimes beat donors. It just puts us non kitters at a massive disadvantage, especially if kitters are using multiple kits (or invisibility potions. They are really OP).
For example, I was getting stuff out of a chest and donor came up behind me and killed me in one hit. I didn't even get a chance to actually fight him.

Any Other Information: If you cannot go through with my suggestion then please at least make it so you can't use more than one kit in an arena.
