In my opinion the game mode was made to cater only to people grinding BB6s and/or using super crews.
I have not experienced much crew death at all, and the XP is well... stupid, plain stupid.
From my playing this weekend:
CV xp.... is a joke. Made a game mode that essentially eliminates the CV play... well done (FAIL!)
SS xp... is better, I wouldnt say its great but better. (not so FAIL)
BB xp.... is stupid. Honestly why dont you just enter the room and have the game hand you your SD ship. I was amazed at how absolutely BAD you can play and still get 3-6 times what you get in playing AWESOME in a GB. (SUPER EPIC FAIL)
Also all weekend, only lost 2 experts (skilled) and 4 recruits (rookies)... so much for that crew death making the insane XP offset right?
I also noticed this is the game room to farm in BB6s because you can make enough credits to warrant brining it out every time. Not sure, maybe I missed the point but werent you supposed to have to pay out the yinyang to use them? At one point I made more credits in this room in a BB than ever imagined possible...
