Hey ms.mintus, I’ll take a while to process all your ideas, but I can already say that your Idea 3 is being somewhat tackled on version 1.20 and that the achievements are a cool addition :P.
Regarding the dodging, we won’t be adding real-time or QTE to the battle system to not subvert it or make it overly complex, specially since there already is a passive dodge effect, however the spin effect could be a nice visual addition for parrying for example :).
