Backstab can also just be modded out.
That is well and good; people can ignore or mod away much of this, but will always be aware of the fact they're engaging in self-nerfing behaviour, playing at harder difficulty with no additional reward for the added risk.
Also, can Backstab be removed from enemies? If you don't install mods, then you can't just ignore the presence of backstabbing because enemies will do it. If you do install mods to remove the mechanical benefits, will the enemy AI still try to Backstab?
I also want the game to take facing into account (since tbt DnD doesn't have facing by default because it makes it unnecessarily complicated, but a video game with models have facing -- visually speaking -- by default) instead of just giving bonuses for being on the opposite sides of the target.
Facing would also work to solve Backstabbing. According to the facing rules, if someone tries to run from in front of you to behind you, you have the option of using your reaction to
a) spin in place to face the enemy
b) make an AoO as the enemy is leaving your reach
Of course, jump+disengage invalidates ^, but baby steps.
