The PVP they are talking about on player run shards is macro driven. When I played on Divinity I just used a macro program to record several key stokes, no targeting.
The real UO pay servers hosted by mythic has had combat totally revamped and due to it's diversity and added complexity is far Superior to most player run shards.
If I was to play a game UO again I would play on the real servers. The game still needs a new data base and updated client so I hope they finally decide to UO2 into production.
