This article has made me feel better. I've been very active on the forums as of late, making suggestions about what PS2 can do to add to the meta-game and depth, but this reassured me that SOE still hasn't implemented most of the game yet, and that when they do the depth will return.
That being said, it is important to say this, and I really really hope you read this: Be careful on borrowing ideas. Its ok to use the combat styles and what not of other successful games like Battlefield, but do not sacrifice your own style. You have the opportunity to create a market of your own, the MMOFPS market. You are going to have your game played by more than just COD and BF players, by more than League of Legend guys and Team Fortress people. People are out there right now that PlanetSide 2 is the last game they'll ever need... until PlantSide 3.
Do not sacrifice your core philosophies, what made the first game great. Sacrifice the parts that failed because of technical issues, wrong implementation, or what have. Figure out how to innovate these things and bring them to the year 2012. You are making a re-imaging, PlanetSide 2. It should have as much of the PlanetSide style as possible.
