I was informed yesterday by an F2P player that he/she could not do any Flashpoints. He/she kept getting error messages when trying to access it. Also every time there was a mission complete that gave items for his/her companion, he/she could not access them. Change the F2P mission rewards if the companion customize isn't gonna change.
In my opinion, F2P players should get access to trading, companion customization, and personal appearance customize. Seems silly to limit them with those.:
