First i would like to warn you about rets upcomming changes, its kinda hard to say if its nerfs or buffs before TPR is up. (there is currenlty alot of arguing and they are not even close to beeing the final changes)

I can seeing this setup doing well against teams who arent that good, aka you should be able to hit 1700 or maybe even 1800. Your hand of freedom will certainly not be for your healer as you will to often find yourself slowed by dks,frost mages and warriors.

Hand of protection helps your healer but it sure counter you pretty hard aswell.

One of the changes upcomming for 2.3 atm is that crusader strike does 25% less damage but have 25% shorter cooldown aka damage is not changed but the ability to burst is.

A good team will mass dispell you to the ground im afraid then drop fears and frost trap,frost nova,dececration,pircing howl etc.

Bursting down a warrior or dk with 30k hp without mortal strike isnt easy, both got good ways to migate damage in addition you got pain suppression from a priest + maybe a hand of protection from a healer.

Hand of protection can be saved for your healer, but it realy doesnt help vs counter spell wich is one of my biggest problems atm even with 4 grounding totems. A rotated hand of sacrifice should make your healer pretty much impossible to kill however. Hand of freedom has to be saved for yourself though or you will find one paladin slowed. Expect them to train one paladin while a rogue stun locks another one, aka you will only dps with 3 paladins and the burst will fail. When you finally use divine shield you lost since they will run away and reset the fight, then drop a aoe fear and win the match.

Teams without a clue always say "NUEK the main and he will die", they charge in and you wipe them in less than 2 seconds wich should be pretty fun!
