Most of the co-op abilities make use of triggers. This includes Blaze's Enflame ability. Just look through the Co-op trigger folder until you find the one that says "data utilities". The Enflame trigger is somewhere in the Tychus folder.
I have been working hard the past weeks and I'd say the next update is about 2 thirds done. This time more content than just a single mission will be included. I have also introduced smaller quality of life changes to all of the past maps: The Achievement popups are animated now! ^^
I actually watched a bunch of other videos regarding this topic already and oh, boy! Wether this is Activision or Blizzard itself, this is just disgraceful. You don't treat your fans like that! I have never ever seen something like this in YouTube history.
What if Blizzard introduced the option of community made coop maps? Like, custom maps you can play and still level up your character? I think that would open the door for a lot of interesting concepts to be explored (alternate timelines, etc.) while actually rewarding you for playing.
Sounds like a great idea! I once thought about doing something like this in SCII, although my attempts were pretty much failures. Making a ship system work seems pretty much impossible in the galaxy editor. Anyways, if you need someone for UI and achievements, count me in! (I can send you some of the prototype mission launch screens I worked on if you want.)
