I've heard the haste "soft cap" is around 430, I currently have 479, but haven't been able to test in a raid setting, since I didn't change anything prior to yesterday's raid. If it's the case that 430 is around where you want to stop, do you just start using strength/mastery gems in haste/mastery place to balance it out?
Also, the 23 atk power 28 crit leg enchants should be way ahead of the 19 str 11 crit in terms of value, yet I keep seeing the latter labeled as bis, any reason? other than just it's been forgotten? (edit: apparently they still show +23 atk power, but only give +8, nvm.)
