How is his advice flat out wrong when you recommend exactly the same thing? He said take unlettered mods and you said stack secondary stats. Unlettered mods are the ones with highest secondary stats. He says willpower is best for your dps and you recommend all willpower augments. Nothing you recommend went against his advice in the slightest.
This was exactly my thought. He says I'm flat wrong, then gives the exact same advice I suggested.
Take unlettered mods. They are better. End of story.
