Master and WoG

[PallyPower]

Since the patch WoG has been buffed, and the duration on illuminated healing has been increased. I have been noticing in fights such as baleroc and shannox that World of Glory and Illuminated healing are much higher on my healing meters than they usually are. I did not save the log of our heroic shannox kill, but here is one for normal baleroc, just to show. I was wondering what you holy paladins did for heroic baleroc. Did you stack mastery for this fight? and did you put 2/2 into eternal glory?(I often put 2/2 in this talent, but for some fights I can go 1/2 or 0/2 on a fight where i need pursuit of justice, and depending on how many yards I need on my judgement) I find that If I am not constantly spamming the tank, they have a much higher chance of dying than in the previous tier of raiding. This results in more overhealing, meaning more healing from our mastery. I was just wondering what you guys think. Does more mastery improve tank healing significantly? Would like anyones opinion, my guild should be working on heroic baleroc shortly. http://imgur.com/URuW9
