I feel like continuing to focus on 1 or 2 heroes per cinematic is a poor move and will result in us getting cliff-hangered when Overwatch finally dries up and Blizzard moves its cinematic team off of it.
Please, get Torb and Bastion to meet up with Rein and Brig. Get them to go to Gibraltar to meet with Winston, Mei, Echo, and Tracer (and whoever else decided to show up). Genji, Hanzo, D.Va, Mercy, Soldier, Ana, etc.
Get them to fight Talon. The Doomfist vs. Tracer, Winston, and Genji fight in Doomfist’s Origin Story was amazing. I want to see more of Talon v. Overwatch, especially now that there are more Talon members.
EDIT: Also, try to fix some of the plot holes. At least put up a post confirming and denying some of them. For Example: Deadlock was founded in 1974, by Ashe, who is 39 in 207X. You could say “That was a reference to the birth year of the designer.” “We used 1974 because Overwatch was originally going to take place in 201X-202X.” “1974 was just a placeholder date.” or something.
TL;DR: Get us at least some substance before you can’t anymore.
