[Disc] 25 heroic: is low Spirit build viable?

[Hypasonic]

Well since this thread is about 25m, you have a lot of mana cooldowns available and can easily regenerate mana during the kite phases, I don't ever need any mana cd's on that fight and I run with 7.3k spirit and I'm gonna try this reset with even less, it's just not needed.

I run 6-6.5k normally, and the highest I ever go is 8.5k if I feel that mana is a problem for a fight. So it's perfectly viable as long as you have the legendary meta gem. As long as you're not going oom, you can sacrifice spirit.
