You know what might be a pretty smart approach: if your current playthrough (your savegames basically) wouldn't get affected by patches unless you choose so.
This is kind of hard to do... but I guess it is doable if you keep that in mind during the developing process. You would need some internal patch- or buff/nerf manager.
Then your current playthrough wouldn't be affected by patches and you could finish the game without disturbances from nerfs that potentially destroy your character idea.
In the next playthrough you then will use the newest mechanics version.
Because that's what annoys most players I think: that the character they currently use changes while they carry him/her through the game.
