On the other hand, I wouldn't mind of they got rid of the sharding, as in Dromund Kaas (1) and Dromund Kaas (2). I don't mind crawling over other players in the "open world" portions of the game, but I like being able to get away from that and focus on most of the major quests without the distractions of non-group players.
I am talking about the open world, might be confusing me using the word instancing, so lets say sharding or phasing instead.
My point is that there are too few players in the open world zones, and it ruins the MMO-experience for me.
