Hear me out. Have you ever played in a Flashpoint with a Free-To-Play player, who is probably new to the game, and they press Need accidentally on an item for your class. They're apologetic but cannot trade the item to you because they're Free-to-Play.
Subscribers should be allowed to initiate trade to a Free-to-Play player.
I know this belongs in suggestions, but lets face it, that forum rarely gets a developer response and I would like to see one here.
