We'll have to agree to disagree on your comparison because you'll never convince me you did not pick the one rule that makes very little sense in comparison. Now if you'd grabbed Initiative, or Defense, or PMS limits, I'd have agreed with the stance that nothing's final. But the one thing that was just an event-stop-gap is just plain silly as far as I'm concerned.
And yes, I'm aware of the defense-change. The poster said Rea+Int was for both ranged and melee, I got a houserule on that including the melee skills and the bonus added by full defense. As for limits, I don't have those since I have zero intel on them. Keeping track of a different initiative score and a different dodge-system is already enough of a task when the printed characters need manual adjustment, with future prospect of a higher-than-six character improvement system but unfortunately without a recoil rule, because it's unfair to introduce that after chargen when they already bought weapons based on the 4e recoil rules.
