I think these are pretty fantastic buffs, honestly. For raiding, Brew-Stache was the best golden trait to shoot for anyway, now it's just making it that much better. As secondary stats increase and haste naturally reaches higher levels, the amount of uptime will be nice. The armor is going to be a huge boost since we're on the low end of armor right now as it is, so any increase will be significant and not affecting any major diminishing returns. It's why the darkmoon fair trinket is so valuable at the moment.
