MK variants to weapons

[(XBOX)XGN DrFeelGood]

With the beginning versions of weapons the MK variants had their upsides and they are few; but the idea can go to full scale. We get weapons over time that are power creep based and are dominant in a area of the stats before unique mechanics or grind walls are integrated. Why not get the option to take weapons to the foundry and refine them for stat improvements up to MK 5? We recently got the Tatsu as a new melee that requires Kuva to craft. The reason to look into the idea is because of the story concept of the ‘Multi-verse’ and in one possibility there are weapons that can be infused with more materials for better improvements. If it was to be implemented, then Wraith weapons can be infused with some materials with Kuva, then Primes with Ducats, and Vandal with Void Traces.
