Well, I wasn't going to wait for the devs to implement free trials over Christmas, so I gave it a go.
Here is the most positive review of the feature I could put together for you guys.
This 99 Diamond Feature is THE most confusing and badly thrown together piece of rubbish I have ever set my eyes on.
Oh and It doesn't even work properly on the Phone App; If you are doing a mission in one location, and a convention is on which you are doing as well, then try going to the Party you had going on.... It then asks you to buy Polyarmory - despite the fact is is actually active! I had to go back to my PC to be able to complete the party at the same time.
The focus between convention and alternate mission is jumbled, jumping apparently of its own volition from one to the other. It also excludes all missions in the location of the convention from selection in the alternate mission.Completing a alternative mission will result in the game automatically switching your focus to the completed alternate mission - making you complete it (eg watch a fight mission, complete a skill check) before allowing you to change focus on a convention regardless on the fact that the show may already have been completed. It doesn't work the other way around though - if your focus is on the alternative mission there is no notification of completed convention shows, leaving you to guess its completion. If your focus is on an alternate mission there is a countdown timer displayed, but this disappears if you switch focus onto a party, preferring to display the time to convention completion instead. The display window for the convention and the alternate mission are identical in appearance and dimensions, resulting in disorientation between the the alternate mission or the actual convention.
This disorientation was so frustrating that I chose to deliberately NOT activate a mission in the alternate during a convention, defeating the entire purpose of having the feature in the first place.
After a while, you develop some kind of an idea on what it was doing; And, on the Desktop side of things, the game did allow you to perform multiple tasks at once - with a mandatory added degree of consideration in regard to what the game was throwing at you each second. Sadly, in a myriad of multi-tasking, the interface and implementation of switching tasks and auto-focus shifts rendered the benefits of the feature ultimately pointless.
