They removed kits from CTF for this very reason, that the donator kits were too op against non-donators. Instead, they implemented a monetary multiplier depending upon your rank. I sort of feel though that they left KitPvP with these kits since it's in the very nature of the game. Sure, it paying to win might not be cool, but if that's not your cup of tea, there's Hunger Games and Capture the Flag where every player is equal.
I am sort of neutral to this suggestion as either way I don't use KitPvP enough and earning more meebles per kill is nice. However, those that regularly PvP here might be upset, especially since CTF was changed from this format.
