/jp/ - Otaku Culture

I need some help /jp/. I'm playing a pet-centric character and I recently got a Great Race of Yith. I have her decked out with four artifact weapons that I took from my Varuna (who is now in the dojo). From observing her attack patterns, she does use them, however, she uses them long after she has finished cast debuffs, and it makes me wonder if I'm wasting the potential of those weapons on her, and should instead get my Varuna back in my team.
Another thing, I gene engineered her a bit too hard with realizing it, and now she has a speed penalty, her speed is still over 140 though, which I hear is a magic number for some reason, should I sacrifice some of her tankiness and get her speed back to normal?
