It's certainly been brought up in discussions before, but not for a very long time now. Honestly I don't think it plays well with Cogmind's design. I mean the name of the game is meant to be adaptation, and the
only thing that really even sorta limits you as you get further into the game, perhaps "class-wise" in other roguelike terms, are the slot evolution choices you made before. I don't like the idea of undoing that.
BUT, having said that, there is a new feature planned for Beta 11 which sorta falls into this category... uh, temporarily? You will see
I will probably write about this new concept on Patreon at some point before long. It was planned for Beta 9, and has now been put off for two major releases, but no longer!!!
