No new in store releases and few PSN store updates (which didn't go up until late Tuesday.) There doesn't appear to be nay new games, but games changing system - Zen Pitbull to PS4 (with Cross-Buy) - and games getting bundled.
Played the Saints Row IV DLC. They're cute but slight. The Saints Save Christmas quest is a lot more developed than Enter The Domantrix. Enter The Domantrix enter point is it being unfinished deleted scenes and it embraces that, but it's still not quite enough to overcome still being unfinished DLC. I wouldn't get it unless you're getting the season pass.
Depends on the group. I'm 11/12 heroic 25man on my main, and we're still working on LK. We've never kicked someone from the raid for the wrong talent build, but our class leads will work with people for it.
