WFB has been working with that table over 15 years because of how much sence it makes. You can implement something else in Ninth but in no way shape or form have you argumented how it would be technically better as the old.
As people have been saying time and again in this thread, and largely been ignored, the evidence that the table isn't working at properly handling what it's meant to represent has piled up higher and deeper over those 15 years. Every single rule that uses anything else to represent skill at arms and effective ability to hit the enemy and avoid being hit, whether it's re-rolls in this or that situation, additional +1/-1 modifiers to hit on top of what the table yields, ward saves to represent shieldwalling or doing a little dance to avoid being hit, you name it.
Having a robust and versatile core game design that can handle all kinds of situations is preferable to piling special rule upon special rule on a core system that by itself is inadequate at what it's supposed to do. It makes for a much more streamlined game and creates much less oddball stuff.
