1. Not only can you not get to enemy faction players starter planets, you can't get to there second planet (Capital) and although you share the 3rd planet, you can't get to there area's. The first chance you even have of seeing any open world pvp is the 4th planet, in your early 20's.
2. The point of a PvP server is to have no restrictions on open world combat. Getting owned by a higher level Assassin? IT'S A PVP SERVER. If you can't hack it, roll pve and carebear your way to 50.
3. BioWare has stated NUMEROUS times that it is also opening servers on launch day, so you and your friends who are so absolutely horrified of some people being higher level then them can roll on a new server on launch.
You have absolutely NO reason to whine and complain. BioWare has your unreasonable demands already covered.
