In before people screaming repost!?!!?
I would like to say that there are several other threads like this who explain FoTW for paladins on vezax, however this trick works differently.
I guess 90% of you are familliar with the new prot/holy paladin pvp spec which basicly runs around having alot of stam and SP and benefitting from the deep-prot talents which give SP and crit.
This spec is a variant of said specs, Talent Calculator - World of Warcraft.
It has the same healing power as the pvp prot/holy pvp spec, which can have flashheals crit for upto 8k and HL for upto 18k in pvp gear
However blizzard has been (reasonably) smart, and made it so that if you spec to deep into the ret or prot tree, your effectual healing output will be halved.
But still in naxx25 gear and fully raidbuffed/flasked I still am easily critting 12k FoL and 35k HL (critline record is 38k), so half that and you still have very decent heals, about the same you would normally have, and the ability to never run oom due to Spiritual Attunement.
This has been tested by me on vezax normal mode with quite crappy gear on heroic yesterday, I only needed to tap out of the mana well once instead of the usual 3-5 times, so I can see myself not needing it at all when I get better gear.
Another note about this spec which is untested (will rep you if you test it before I can do) is if this spec works with the +20% stam buff on YS, to see if it works with Touched by the light (the thing this spec completely resolves around).
Another hint on general vezax is this: If you stand in the clouds you can refresh BoL and SS with the mana reduction, but since they arn't heals they don't suffer from the -healing penalty.
