people are like "know classes are best for support and trash fighter" but Terezi and Rose kick ass and don't forget they can whip up some useful alchemy and craft weapons to channel their aspect and use those like know other ;D

See, the thing is that, the Know Classes are better for Support- When it comes to their Raw Classpect Powers, comparatively to other Classes. They excel in predicting what’s going to happen and planning ahead and going for what they’ve seen. But that doesn’t mean they cannot be capable fighters- Rose and Terezi’s powers, indeed, focus mainly on their foresight. But aside from their powers they’re just god damn badass fighters, I mean Rose was 13 years old and had just entered SBURB with a pair of knitting needles when she stabbed an Ogre in the eyes and rode his body down a god damn Waterfall. Do not fucking mess with the Seers, they’ll fuck you up.
