343 decided multiplayer to be canonical. I do like the idea of multiplayer to be part of the story of Halo. Who knows? In future, 343 could add top players as legendary Spartans appearing on actual campaign. However, it some kinds lacks contents and some parts do not make any sense. New mode “Breakout” is most realistic and convincing canonical. You have one life for each round. That’s what real training suppose to be look like. Respawning never fits into realistic training. Especially in Warzone, once you killed other by Forerunner weapons, his/her body gone. How come respawn, since you lost your body?
We have great maps from campaign that could be playable maps on multiplayer, mostly Warzone. I like mission 2 “Blue Team” fighting in Argent Moon. I think Argent Moon would be great map for Warzone. It was destroyed, so we cannot see her again. Canonical multiplayer threw away these things.
I think non-canonical provides more contents.
