What to buy next?

[Ironbeef-LB]

I am just looking for advice for what to buy next with my valor points.
My armory link: http://us.battle.net/wow/en/characte...ronbeef/simple
I am thinking of going for the relic since am missing 90 points for it but i am not sure if i should get the spirit relic (reforge the crit to haste)or the caster dps (reforge crit to spirit)

How close are you to getting Fall of Mortality. If it's not something you see getting anytime soon Core will be a good up. The ring is also a good up too. You'll probably see the least amount of stat increase from the relic.

We have only killed cho gall once and having trouble killing him again. so i guess it would be better to get the core but am not sure about the proc if it is alot or just a bit better then tear of blood (up time).
