To be quite honest, the 2016 lineup was awful. I was at the Resort for one weekend last year and Oblivion opened late both days (~9:20 on day 1, after 9:30 on day 2). They also took their time with Spinball. As such, it felt like less of a "perk" (a couple of free rides on Enterprise and CBeebies stuff) and made me wonder why I got up at 4:45am just to get to the park in time for it.
The 2015 lineup was fantastic, I believe I managed 3 Nemesis and 2 Air in that first hour and I was then able to hop to Dark Forest for a few rides there before most people made it up there. It was also actually did its job of spreading people around the park by 10am, rather than the 2016 lineup with just encouraged
people to run to The Smiler first (although they probably didn't go for Galactica in 2016 for that exact reason).
I wouldn't mind a revert back to 2015, with Galactica opening up at 9:30 (especially as I haven't done Galactica yet!
) Alternatively, some arrangement involving Dark Forest and CCL might be nice - you could even throw in Hex, if it's actually available. Not a fan of an X-Sector opening; it just crams everyone into that small, crowded area.
