@dreambled It seems like a good solution to me, because it's rare that you would ever want to gimp your rolls. If it's a rare situation, it shouldn't be the default way that it's done. In fact, if it's a little bit harder, then that's fine as well. But I guess it's just whether or not you value a small but constant good more than a large(?) but occasional bad. Although I agree about equipping a str weapon mid combat being a bit much, I shouldn't have mentioned that as an option. If I really, really did want less damage, I would just leave the high ground or unhide. A bit of inconvenience for one turn every once in a long while is worth two slots in my hotbar to me.

@SLOPOrion I understand that sneak attack works only once a turn. To clarify a little, although the OP suggested a toggle, in my thread I actually suggested that the attack button be upgraded to always sneak attack by default if the conditions are met. That's probably even worse from your perspective! Anyway, in terms of 2WF, if you miss with your first attack, it shouldn't use your sneak attack. I reread the 5e feature, and it says the damage is applied to a creature you hit, so if you miss there shouldn't be an issue. You still have your sneak attack for that turn. In terms of the other scenario, so the first creature you would hit using your full action and the second creature you hit with your bonus action and apply sneak attack. Truthfully, I'm cool with sneak attack being automatically conserved if the damage would go to waste. I don't know if it's realistic, but that can also be good design, if it makes the experience better and less frustrating. But in the scenario you gave, you have your full action for that first attack. You can't deal 4 damage in any other way? You can't throw something, like a dagger in your inventory? Or just let another party member deal with it, and use both attacks on that other enemy? Do you really want a dedicated button for this over two spots in that tiny hotbar we have? I really do believe that if the vast majority of the time you can't benefit from an option, and even when you could you probably don't actually need it, then it should not even be in the game, let alone the default.
