yes, that was my consideration. especially since bashira has better attack speed and 600+ attack with prince buff iirc. also, def is probably 300 but in the end, everything is take with a pinch of salt and just estimates. a lot of things you won't be able to tell until you actually experiment with it yourself. I simply came up with the hypothesis, but at this point I'm done with experimenting and I have already achieved what I needed to.
also, wiki is not completely wrong. there are scaling on some (usually the scrub mobs) which I have personally experienced before between 400 kill map and 500 kill map in a previous dmm subjugation before. same applies to current dmm subjugation between 500 and 600 kill map.
