I just don't understand. If people are already using lower iLvL items because it has better secondary stats, reducing their effectiveness is just going to make those stats more valuable for them to pick up. Buffing the amount of crit/mastery you get on a higher iLvL item isn't going to mean jack if your class needs a ton of haste to have a decent rotation.
I feel like they're jumping through these hoops to try and fix stats when giving us reforging back would have been easier... Then people would be equipping the highest level items they had more often.
