If that experience chart(unofficial) is at all correct, I will never even come close to Paragon 100, or probably even Paragon 5. I do like the preview changes for the rest of patch 1.04 though, and I'll probably keep playing D3 on and off as new patches catch my eye, etc.
This paragon system isn't the worst thing that's ever been done in Diablo 3, but the sheer scope of the grind involved means it will likely have almost no actual effect on me or what gear my characters wear. My barbarian has the most MF of all my guys, at around 240% pre-NV. No danger of hitting the cap anytime soon.
