1. I agree with the Op, I don't buy single player games for the chance to play lag online, and see who has the best ping.
2. I have tried many different types of Online multiplayer games, and except for a very few turn based games, Ping is king, and for me they are just a waste of time. [ I agree that Skill is also a contributor to the MP action, but lag is the killer, and fool maker, there will never be a fair Online twitch game play, latency, and lag will always make a fool of you ( I miss my lan parties, but they due to DRM, seem to be pretty much a thing of the past ) ]
3. I buy Witcher, and Elder Scrolls, and Bio-ware games for my own personal fantasy escapism, and have no desire for Multi play.
4. I think it is fine if they want to add it for those that do, but I would prefer they put the extra effort into more quality, and better optimized Single player RPG.
EDIT>>PS And I certainly don't want it to ever have any Bering on my Single player experience, as the idiot ( a person perceived to be lacking intelligence, that is my personal opinion of the person that came up with that stupid Idea ) did in ME3....
