Been fiddling with Mr. Robot for a little bit and while changing some of the weights, I noticed how it would suggest using +320 haste vs +80 int +160 haste. As I'm at work I can't do any math but if memory serves, int has a stat rating ~ 4 while haste is ~1...so....320(1) vs [4(80) +160(1)] = 320 vs 480.
If this is the case, why would El Roboto ever suggest using a yellow vs orange gem?
