I'm excited based on what was actually written. YMMV
1 raid at a time, yes please! I haven't touched cPit save once or twice in the past year. HAAT and Rancor were on sim. HSR every 3.5 days became too much for me a few months ago. So I've been doing 0 at a time for the most part since last summer.
Participate in the raid at a time of your choosing, er muh gerd, YES! When I started this game, I had one 10-mo kiddo. Now I have a 1, 4, and 6 year old. It's SO hard to get in and do HSR during the small window I have. Knowing I can do my raid stuff on my own schedule will be such a huge QOL improvement for me.
Shift to cooperative rewards. YES!
Faction restrictions... if it means what they said about design space and they actually release a new raid every few months, sounds great to me. Besides, with what GAC is turning into and how little the new TB has inspired me to build squads, I'm looking forward to scratching that PvE roster development itch.
Hopefully CG gets the rewards right (the part in bold and red).
