they seem to have disappeared for a while. i was checking every day but I have cut back
The last thing they did recently was upping the prices of existing costume sets. Before that they allowed people to purchase an account-wide unlock for the global cap if they were silver. Currently they are just, well, doing little other than absolute necessary bug fixes. I don't think they really work full time on the game but only on the game once in a while, and probably don't fully care to do so anymore. Not with the kind of community thats left anymore.
I've been playing diablo 3 again, on my old demon hunter after I got a season wizard to 70 for the sake of some transmog(costume) unlocks. I notice the drop rates had increased alot, as I got three maurader set pieces today in a short time span to my surprise. A shame that two of those drops were pieces I already had from previous play sessions. At least that game gets stuff. Course i'd be playing city of heroes far more than diablo 3 if it came back. I'd take a guarantee drop system like CoX's incarnate system over an rng within an rng within another rng system diablo 3 has.
