First off, there's some things I need to clarify. First off, the video(s) I'm actually talking about.
These two videos are the backbone of this entire essay and I personally consider them to be required watching in order to understand this. I will also be using his tiering system, but with some slight edits. I will be offering any concise reasons for tier changes, if need be.
This section mostly acts as a quick reference guide for what I'm talking about to the unintiated. Someone outside the fandom's bound to find this interesting, anyways.
Bloontonium: Commonly assumed to be the main power source of Monkeyopolis and other major monkey population centers. Also explicitly mentioned in the weaponry and/or descriptions of some towers.
TSG/VTSG: Acronyms for Super Monkey's 5-0-0 (True Sun God) and 6-0-0 (Vengeful True Sun God). I feel it worth to mention that VTSG's name is fanmade, but Ninjakiwi uses the terminology as well.
Paragon(s): A new kind of tower/upgrade Ninjakiwi introduced in update 27.0. Yes, they will be mentioned.
I will be the first to say that I do mostly agree with these rankings, but the guilty tier is where it fails for me, namely with Benjamin and Gwendolyn. Adora, Obyn, Ezili and Sauda I will get to later.
My main problem with Benjamin's ranking here is the reasoning. He states in the first video that he's a war criminal under 'cyber warfare' laws, which 1: don't even exist yet and 2: would probably not include his niche in the game[1]. I might come back in, say, 10-20 years when these laws actually get passed but for now he's innocent until further evidence is given, either in universe or otherwise.
Gwendolyn, however? That opens up an entirely new argument, one that I also happen to have some thoughts on.
