F2P model can help to bring players in game / game is only purpose - bring money to EA .
What can help here without f2p model? / I personally would like the following : mature content, mature rating of game , more character customization (social fashion gear, mounts,fashion weapons? more fun devices) , remove pvp gear - other forms of stimulation activity among pvp players (as special war areas with dangerous environments-vehicles-aircraft and special mechanics), more exploration - random single events / quests , improved means of travel between the planets - if not seamless world - or at least a system of instant teleports between major worlds (bypassing the player's ship).
in the initial stages of the game - or at least the possibility of moving from one faction to another in a special quest. Ideally, the separation of content into two parts should not be.
And many other features, can't come up anything outright:)
