In your dispatch of your undergraduate legal course, you mention nothing about being first to use a name, which in US law seems to be the basics and is apparently enough to own the right to be alone to use that name or at least, ask for no infringement from anyone else using that name after you started to.
By infringements, we can easily see them, Pinky sumed them up (Google search, Twitch vids, WZ customer service). These were not happening before Activision use of this name, and wouldn't have had Activision chosen any other name.
Also, you're saying Activision has done no wrongdoing. But what if Activision did a thorough research about the name (would that be surprising from such a big company, with so much at stakes ?), and found out that Warzone was used a lot, and marketing team said : hey, let's just use this name, nobody would be allowed to complain, and with a global expensive investment in marketing, we'll gather attention from anybody trying to play any "Warzone" related game, after a friend told them about playing it, even when they were not talking about COD. This is kind of a way to steal marketing efforts of all small company having Warzone in their name, a bit like in your Coca-Cola example (well not exactly, the related point is about stealing marketing effort from someone else).
Say you invite a friend to meet you on Warzone to play it online with you, the "source" (Fizzer's game) has a good chance to be confused with COD game. That's infringement and what your line "trademark law is about protecting source identifiers and making sure consumers aren't confused about the source of a product" seems to actually be defending.
Also, I don't think we fall in the Dove example, because in my above example again, inviting a friend to play Warzone with you is already confusing, despite not being a video game played on a console. So the scope should be "online game", not specifically "video game" or "PS4 game". And both COD and WZ as we know it are online games.
Also, this would mean that one could come after everybody on a brand, use it, and buy the global recognition for the word with expensive marketing investment, including paid SEO (how else would warzone.com appear so down) and TV spots, benefit from efforts made so far from all related small business, and basically kill those indie games.
Also, you're saying "Warzone" is not specific enough to be branded. So neither is "Black ops" then ? Are we allowed to create a game called "Black ops" and hopefully attract COD players ? That would be cheap marketing if allowed.
Also, you say "Warzone" is a common english word. For me Warzone is the contraction of 2 common english words, war and zone. Of course in URLs most words are contracted (using dashes would look ugly) but on a legal view, this word does not seem so common and this way contracted makes it quite unique IMO. I mean, I'm looking for a translation of "warzone", I can't even find it

I'm not saying you're wrong, I'm just raising points where I would appreciate clarification.
