That's pretty much it; if we compare, point for point, the benefit of putting a point in Will versus putting a point in Def, the Def may help more against physical attacks than the additional invoking level of 200% Will, but Will helps against not just physical attacks, but magic as well. And if you divided the points that could have been spent in Will evenly among Def/Res, they both get a much smaller benefit.

It's exactly like comparing Vit to Def/Res; we can't have enough Def/Res to render the Vit (or in this case, Will) negligible. We do reach a point where it's better to add more HP instead of more def/res, purely since HP enhances survival against all types of damage, not just one.

I'm not saying one can't make a good build around this - since we most certainly can build for Def/Res regardless, and taking SOME will for the FP is a good idea regardless. I'm just not sure about the 200% scaled will thing purely since I've managed a build with 60 scaled will (alongside 40 Def/Res) before, and I'm not sure it'd be fair to give that build a harder time to get broken compared to a build with 30-40 Will that has, say, more Vit or Cel or something.

If you all think it's a good idea, then by all means, I trust your judgment. I'm just expressing my concern with one aspect of it.
