I don't know when the last time yall checked how many totems shammies get was... ?? there are some already that don't stack and QQ more if you don't like the non-stack change for mana totems. There are so many totems to throw out there that other classes don't give that there will always be a utility use in bringing shammies to raid. WF, Wrath of Air, the other wrath totem that elemental shammies get which its been so long i been ele i don't know the name of it; you've also got cleansing totems that make it easier to not have to waste mana every two seconds casting dispells; there are earthbind totems;aoe magma totems; tremor totem that gets rid of fear effects without having to have five priests to buff the entire group with 2 minute CD. many more.
There used to be a time when you could stack the use of any potion in teh game for boss fights pre BC.. we got over that and forgot about it and now we use one a fight. did that bring an end to the game? no. it made you better players so you didn't rely on crutches.

sigh. so many QQQQQQQQs
