Welp, time to catch some flak, I guess. You see, I actually like the Imperium. Now, I don't think they are "good guys" in any shape or form, Emperor forbid. I just like the style. Mark III Power armour just looks awesome, fite me.
AdMech is also cool, although I disagree heavily with GWs decision to make them steampunk/Da Vinci styled. Should've stuck with Blanche-esque horrific post-apocaliptic techno-barbarianism.
Finally I will say this. I've been around multiple Warhammer communities and multiple RPs. And there's one thing I have learned - all factions are cool in their own way, it's the fans that suck and make everything terrible
