Reading is so hard. I have never disagreed that strength is not always worse than 2 haste. In fact I have repeatedly stated just the opposite. At the end of Cata I was gemming haste precisely because it simmed better and performed better. As for your attack on my current gemming, you don't know what you're talking about. I'm gemming haste, per the stat weights I get simming my current gear.
What I have been stating is that there is no single "hit this # of haste and then stop gemming haste". For someone with a 463 weapon, the # will be very different for someone with a 509 weapon. For that matter, at BiS level 2 haste > 1 str even with reforging and gemming and enchanting for as much haste as possible and using a trinket that procs haste.
