I don't think its a good idea.
1.) It takes lots of resources which could be used in better ways
2.) 3D space combat is a complete different game. I don't see the benefit for TOR
3.) Only a small number of players will be interested in such a feature. 3D space combat is much too difficult for most of the players.
they have different design teams for differerent aspects of the game..i see it as a huge benifit,seeing as there is currently no pvp space combat,and it came out as #1 in thier poll so i guess alot of people are interested in this feature
