I'm still on 2012 versions of autocad running just fine on my old R61 xp laptop. I've got Maya 8.5 and under running on my desktop coupled with xfrog and  other plugins that were later fully integrated in Maya.

I see no reason to downgrade to subscription for what I do. There is plenty of other software out there that is perpetual based that is better for creating specific assets. An example would be reallusions character creator.
