Just a quick heads up, there's a bug atm.  If you were previously a subscriber, and decide to play Silver and DELETE (as opposed to convert) a Freeform char, so you can free up a slot to start a Silver AT afresh, you may lose the slot.  I learned this the hard way and am waiting for updates on this issue, which is known, and for which a fix will be incoming at some point.

The slot I lost was in an extra slot I'd gotten for getting a toon to max level, so the bug may not affect slots within the normal allowance as was (when the game was p2p), but just be careful.

Update, this issue has now been resolved with the latest patch.  Playing CO again on Silver with one of the ATs - there's like 40 instances of MC!!! I'm in shock!!! 

Looks like the game's rocking and people are having fun.  Well done Cryptic!
