Not at all. Like Elemental Balance is at 8 because it gives 2% crit dmg till 8 and only 1% after. It’s a breaking point. Same as Mark of Torment, Conversion, Ravenous Earth. Just play around in GT and see how exactly the values change with each point at different ranks. Other than that all skills are either as high as gear allows or at one point.
Build is painstakingly optimized. The only thing I would change here is that I’d soft cap Mirror (12/12) because it’s basically the main means of survival but build is optimized to the pilot. Oa from Overload seems excessive, and aether res is not an issue, so I’d pull points from there. That or softcap Ravenous Earth for another projectile.
