5 shamans in WoTLK heroics?

[emesis]

On another note, someone said that having more than 2 shamans is bad because the totems don't stack beyond 2? Is this true?

Incorrect in a crazy way.

One totem that used to stack pre WOTLK no longer does (Totem of Wrath). So, you just need one of those.

Other totems that used to stack like Healing Stream still do.

Some totems that previously did NOT stack now do - Mana Spring totem stacks which is hugely awesome. I drop 5 MS totems and thats 34 mana x 5 every 2 secs, for a total of 425 extra MP5 continuously while in combat.

Also, fire totems just got majorly buffed (and stack) - they don't generate ANY threat and magma totem got it's spell coefficient nearly doubled.

Heroism/Bloodlust is now raid-wide instead of party wide; and using it gives you a 5-minute exhaustion debuff which has to wear off before you can pop it again. This is too bad especially for arena but otherwise not a big deal.

So, shamans still have great synergy. I am bringing up a tank (78 DK) though, for heroics.
