i think part of the problem is that Haste in fact can’t really be “charted” the way you guys want an attribute to be, which is part of why it’s discounted. Ret paladins end up having now so much to do with random procs that its hard to chart.
I’m not saying this traditional build is bad at all, just that I have a hard time trusting this kind of advice when there’s so many giant holes in the reasoning.

More haste will actually give you more chances to proc Divine purpose.
Haste gives you added chances to proc Art of war.

Divine purpose doesn’t…..disqualify haste the way you’re describing it, it actually can, in theory, factor it in.

I see this reasoning all the time.
On my Ret paladin, i kept getting haste stuff, so i thought, alright, let’s see what happens. I’ve been topping the DPS charts on heroics and raids over the ret paladins using this “traditional” build very consistently. Some of these guys have better gear than I do. My haste build is beating them in DPS. These aren’t randoms, these are people I get to run with time and time again, and time and time again, their build built off this mechanic falls below mine.

I started trying haste as an experiment, and now, I’m thinking there are at least possibly things you haven’t taken into account at all.

just checked out a really good raiding ret pally in my guild (my competitor) and just saw his crit to haste ratio around 2:1. can safely say i have some reforging to do now. pretty excited to pick up some more dps!

with my haste within the % range of my crit (but stacking mastery and str) i’m usually finding myself in the top 3 of the damage meters.

T11 2set Bonus – Increases the damage done by your Templar’s Verdict ability by 10%.
T11 4set Bonus – Your Inquisition ability’s duration is calculated as if you had one additional Holy Power.

That 4Set bonus is looking mighty tasty right about now. With a slower ramp up time to get a 3 stack HoPo, using 1 will net you a 20 sec Inquisition and using 2 will be a full 3HoPo TV hit. Overall this is going to be a HUGE amount of our DPS especially with these changes to Mastery.

You should see some vast dps improvements the more mastery you stack around 14% and higher as its a flat increase to CS and TV damage… As mentioned before by Khor, haste is by far the worst stat atm I would suggest looking at replacements threw heroics and rep (hyjal betl) to replace the haste stacked gear…

If you could pick up the right eye heroic it is a nice dps increase and extra hit is always nice cause you can always reforge what you dont need.. Crit is nice but it takes so much to get a decent increase i would suggest mastery vs crit unless the gear has mastery and crit… Also if you have the gold to pick up landslide is very nice if not get avalanche…
