#1. Ignore Holylicious' macro
#2. If you have the T10 2 piece bonus you'll want to use Hammer of the Righteous(with its prime glyph) in all situations, both single target and AoE.
#3. Use Hammer of the Righteous(with t10 2 piece..otherwise use crusader strike) every other attack to generate holy power and
use Shield of the Righteous when you reach 3 Holy Power.
#4. Inbetween each hammer/CS use the following moves in this priority: Avenger's Shield > Judge > Holy Wrath > Consecrate
#5.
http://db.mmo-champion.com/s/53709/ is a powerful talent, make sure you judge at least once before you use shield of the righteous for the chance to get this proc to make SotR crit.
#6. Don't use a tanking weapon. Get a high weapon damage (weapon damage...not to be confused with weapon dps), slow swing, dps 1-hander weapon. This really makes a big difference becuase each CS/HotR you use scales directly with weapon damage, and no matter the swing speed on your blade...the 3 sec CD on those two moves stays the same. Take advantage of that. (the 2.6 sec swing speed wrathful pvp 1 handers are great for this btw...lots of stam and lots of weapon damage)
#7. Your main source of damage, shield of the righteous, scales directly with attack power, so using a strength trinket will also help you in threat.
#8. If you aren't already...use wings when you pull or whenever a dps starts to creep up on threat.
In addition to the above you could get hit capped and expertise to around 30 (with the seal of truth glyph active), also you should take one point out of Hollowed Ground and put it into Vindication...near-free damage reduction.
