I am really excited to see more content added, and personally I love stuff to grind for. It gives me a reason to log in every day, spend a few hours hitting all the dailies for my comms and knowing that I can get that gear piece I want in just a few days! Its that kind of stuff (along with other like long, hard ops, gigitty) that make a game last and people want to log in.
That being said, I also feel you're now going to be throwing so many comms at people that they'll accomplish everything they want inside of a few days, and then you're back to where you were at release with everyone being done with nothing else to do / work for.
Too many comms, too fast
