Yeah, Sid, I would never stack stamina. Have you played hpally like... at all this xpac? I cast heals for under 1k non crit with int and vers stack + flash of light glyph, not about to swap int for stam because you think everything is like a resto shaman, lol. With buffs though I will use ring of pardons + beastbinder and sit at about 5k in BGs, was using int rings for questing today. The only real excuse for telling me to stack stam would be for a bigger LoH, and yeah I wouldnt bother using a 7k hp stam set just for LoH unless I was holding flag with 10 stacks.
I use mindthrust for the int, scales to 7 int 4 stam 4 spirit in bgs and well those are all stats I can use. I would much rather the extra 2 int than a little haste or crit, and dont think I will stam stack with how holy is now guys... its not worth it.
Pursuit of justice is a static +30% speed increase so I sit at +50% speed at all times, I dont FC nearly enough for Speed of Light to be worth using every 45 seconds and I wouldnt even consider using it for anything other than FCing. I dont waste holy power on WoG anyways so I would rather use it for a speed boost.
