Nah... As you can just reduce the strenght of your orc to 5, it's pretty much *proven* you only care about minmaxing. There is literally no other explanation. With a DM, you can negotiate reducing that strenght even more. In a video game, we can't consider an edge case of edge case of an edge case... that 5 will have to be enough.

As for you getting 2, and maybe an extra 2 points for that exceptionally low strenght... Yeah, I take offense to that. That makes not only no sense, but negative sense. If your character has a disability, I'm going to hold you accountable to actually roleplay the consequences of it. The full consequences of being disabled. Not "hidden superpower" special.

A friendly DM might give you a +1 to int. Your orc is not getting smarter than Gale just because he's got a disability affecting his muscles. There's suspension of disbelief and it dies just about here.
