That too. It didn't really bug me all that much, but I definitely see and can agree with your point. Muti billion dollar company and the best they can do is mid 2000's level graphics and animation? Next thing that bugged me, was that D$^&@& movie that started it all off. Soooooooo many things to pick apart I hate to be one of those "I hate x,y, and z" guys, but there were just so many (at the time) cannon concepts and things they threw out the air lock.
Yeah, it's always the fringes of a group that get all the attention, regardless of whatever they might be. I would know because I have to deal with things like this all the freaking time in my own crazy, bizarre fandom.
Since Disney cut all of everything from the expanded universe nothing in the games or books is cannon now only what was in the movies and shows are. But since, Delta Squad was in an episode of Clone Wars they are cannon. So who knows, maybe Disney might do something with them.
here's my idea on the pacifists... Mandos aren't all that into diplomatic things so what if a colony from Naboo landed on Mandalore and started calling themselves mandalorians in the senate... and the true mandos have no idea because the last time they went into the senate building was like to assassinate the chancelor or something like that
Hmmm, not a bad theory actually! Or maybe the true mandalorians just let them take care of political stuff because all that government nonsense doesn't really matter to 'em. Hehe! I mean...that would be like having someone volunteer to do all your busy work at work/school. Haha!
