To be fair, x1 did use Star Pact with his Cyclone setups from the start. He only argued on its utility regarding IK builds – where it ended up to be BiS, too, though, so yes, there is a strong argument for you being right 
Those resists on Shoot’s build are only then a problem if you don’t have max rolled gear… and I strongly suspect them to be pretty much godly on his toon
