One thing I wanted to talk about but I always keep forgetting is the completely missed opportunity they had with Millennium's weaponry. Each larger school has a gimmick in weaponry and while it's never followed 100% (except for Red Winter, so far every single student of theirs still uses exclusively Russian, Soviet or Warsaw Pact weapons) when you think Trinity, you think Bri'ish guns, when you think Gehenna, you think German Guns etc. Hell even the SRT girls have their own gimmicks, with RABBIT squad's being Finnish WWII weapons and FOX squad's being American spec ops during the Iraq War. Hell, even Highlander has kind of a gimmick of using revolvers, lever-actions and other old-timey guns.
Millennium's could've been futuristic-looking guns, instead it's pretty much just modern NATO weaponry which is a bit too generic of a theme. I got reminded of this because they're running Toki's banner currently and her G11 is a perfect example of the kind of guns Millennium students should be toting. The fact that there's not a single Millennium student with guns that are considered futuristic-looking in popular culture like the AUG, P90 or F2000 is borderline criminal.
EDIT: I will give them one thing, the fact that they made Akane's Welrod and Karin's Boys look futuristic as fuck despite them being WWII weapons is very impressive.
