Ok we all know that most of the servers just removed durability from weps so we can't stack spell power (QQ huh?).
Now this i found by my self on the pserver i paly on (if this post is a repost then sorry but i don't search much).
So to get to the point:
First spec into something like this: Shaman Talent Tree
Make sure u get Dual Wield
then equipe any 2x 1h weps u like.
now the bug is here, respec to any other spec u like, e.g ele or resto, but keep ur 2 weps on DO NOT remove them and voila u still have them both, its something like the warrior titan grip old bug, but for a shaman, slap 2x falmetongues or 2x earth living and get to action.
