Now that I've read that thread, I would say that "stubborn" is a very polite way of describing it. I cannot see justification in his stance either. It's actually quite simple. Add up all bonuses to strength. Are you defending? Add 2. Are you attacking? Don’t add the 2. Then at the end, apply the cap. Add sacrifices later. I don't know how this guy can even justify capping strength at 58.
I'm not even sure that it's an attempt to avoid additional work for Nicholas. I'd be perfectly willing to accept an answer of, "Oops, that was coded wrong. The coder doesn't have time to address something that will rarely come up." It'd be a bummer, but I can certainly understand where he'd be coming from. Although, I hope that reason doesn't hold, because I did contribute some money to him for his effort. I don't know if the donations surpass the costs to host this site or not, so he might not even get to keep that money.
I can agree that it's an edge case that likely has no to little impact on the game, but it still doesn't justify someone's claim that max strength is 58.
