I know the attack droid drops from the Nodes! You were asking about the attack charge (buff) weren't you?
And HOW have I been rude to you?
Also, as I was talking to a SGM last night about this very topic (asking for hints on what might drop the attack charge) I was informed that they are not meant to tell. SO if a GM or two from the past has talked about what drops what.. then it was already common knowledge. As a matter of fact, GMs are not even told WHAT drops what anyway, so unless they find out by playing the game itself or from other players then they can't help you, so stop ranting about it.
If you don't want to pay money any more then don't. Who really cares if you do or not? Getting mad at the Devs or GMs for not telling you what drops what is pointless really.
