I'm enjoying the free DLC so far. It's great they added a good deal of content when we had basically run out of things to do. As well as given caps a purpose again.
I remember getting to the end of the raid where you pick up the gold and thought it was rather anti-climactic for a storage room. Not at all what I expected. Then I got to the actual end and it was like "now this is what I expected!" Lags my PC just by looking at it.
Of course there's still bugs to fix. All of the bugs that have been plaguing my sneak gameplay since day 1 are still there. And there's a new bug where NPCs can steal your rare legendary weapons and use them if you die at certain events with them. So I'd stay away from those if I were you.
