So, about that hit and expertise.
For example, say you know a major boss attack is coming in a few seconds. If you're capped, you will know without a doubt that if you hit Crusader Strike one second before the boss attack, you'll have the three Holy Power needed to use Shield of the Righteous. If you're not capped, you run the risk of that CS being parried and not being able to get ShoR up in time.
Will that kill you? Not always. But it's worth consideration.
...but I see you're reforging out of hit/expertise as hard as you can, so I guess you've traded that particular error for a more severe one...?
The one time it would have mattered, you'll regret the choice. I was the same, running under hit/exp cap until that day. I've changed 180 since then and always make sure to run a bit over cap.
I will not go with haste, and it looks like they are gonna get super nerfed in 5.3 or .4
There is absolutely zero indication that there will be any nerfs to Prot haste builds any time in the future yet. Blizzard has said that they're fine with Prots stacking haste--they just didn't like how much Prot avoided avoidance, so they fiddled with Grand Crusader to make avoidance more appealing.
