There is nothing superior with the pvp in modern Ultima Online. It's completely item based like Diablo but much worse with very little skill involved. Unless you enjoy playing games like WOW, Diablo, or any of that other crappy Class A > Class B < Class C < Class D, etc... There is very little if any skill in a class based pvp system. Those games are only based on a controlled environment in order to get the most bang out of your buck, nothing more. Only a fool or a completely clueless person with very little understand of the game today would ever play on one of the current production Ultima Online shards.
I would not play either currently but it sounds like you just flame games don't even play: UO production (It's apparent you have no clue) and Darkfall.
