I understand the chat problem. I generally log on to the chat on this site as well.
As for defense decks. I don't have any support carriers, as when I stopped playing that card wasn't even out yet. I'll see if I can get a hold of a few. Past that, I'm trying to finish the missions that have come out since I left. I'm not at a point that I can acquire either of the other two you named. A daemon spam I can sorta do, just not all that well since I don't have a ton of them laying around.. I got the early strikers, with the exception of atlas.. I still need him.
