Hello, fellow enh shammys. I just got this trinket and I'm wondering how much of a dps gain it is, since most posts that i read says that I need 277 weapons for it to become usable.

This is the link to my armory: http://armory.molten-wow.com/character-profile/Jlavr/Ragnaros, any help would be very much appreciated.

I'm planning on gemming with pure haste gems on the yellow sockets once i get the t10 head and legs.

Pd: I was using Shard of the Crystal hearth in it's place before.
