Benediction - Putting 5 points into this talent reduces the mana cost of your seals and judgements by 15%. To put it simply, your seal of the crusader, and seal of righteousness, as well as your(WoW Gold) judgements for both of these cost 15% less. Helps with mana efficiency while tanking and if you put 2 points into improved judgement which I'll talk about in a moment, you can seriously talk major threat for (Cheap WoW Gold)minimum cost. Not the alpha and omega of tier 1 talents but certainly better than Imp. Blessing of Might. Throw 5 in.
Improved Judgement - Two points into this talent effectively reduces the cooldown of your judgement spell by 2 seconds. A great talent to have, faster judgement of righteousness = faster threat generation. Great talent.
Improved Seal of the Crusader - Putting 3 points into this talent makes any mob or boss or anything that has been judged with seal of the crusader 3% more vulnerable to all melee and spell criticals. This is a HUGE buff to be giving your raid and or party when you're on anything but trash mobs and I would highly recommend it!
Deflection - 5 points for 5% parry chance. MUST-HAVE if you want to take tanking seriously. According to calculations, we require 102.4% avoidance with holy shield up in order to maximize our tanking capabilities. Without a guarangeed 5% in parry you will have serious trouble in reaching this cap. GET THIS!
Changes in the Prot Tree -
As I discussed shortly in a post further down, Reckoning becomes more of a problem at higher lvl instances, and raids than any help. It was a pure solo talent for (Gold WoW)while you were leveling and doing regular 70 instances. When you hit level 70, you should drop reckoning and put your points that were missing from 1h Weapon Specialization into that. It will increase all damage you do while a 1h is equipped by 5%. This includes basic weapon damage, consecration, your seal of righteousness AND your judgement of righteousness. A great talent for higher end stuff and a great place to put the points you took out of reckoning.
