High level planets have max 6 players, no one is doing world pvp in Illum. People don't talk in chat, and i takes around 3 hours to find a group to flashpoints. What is this, a single player game that i need to pay monthly fee for? No thanks.
Now that i'm 50 and i've finished the story i guess... that was it.
You realize that probably less than 1% of the players are level 50 right now. I wish Bioware could give us some numbers, but I can certainly tell you, out of 1.6 million players you are the minority.
Suggestion? Take it easy for a while and roll an alt or go ganking/exploring.
