More mana totem nerfs!!!

We are making a change to these spells so that their
benefits are exclusive in patch 3.1.0. The buffs will be equivalent,
but will no longer stack. Mana Spring will affect the entire raid
instead of just the shaman’s party. We felt that both paladins and
shamans brought too many unique buffs to a group. Additionally, we have
been trying to tone down mana regeneration in large groups, and were
concerned raids would feel the need to stack paladins or especially
shaman to have enough Mana Spring totems. We have also been trying to
get more benefits out of the party and into the raid, and Mana Spring
previously was still a party only buff. With this change, if there is
only one paladin, he or she can bring Blessing of Kings while the
shaman offers Mana Spring. If there are two paladins and the second
offers Blessing of Wisdom, then the shaman can offer healing or
cleansing with their water totem instead.

So now it looks like mana spring is COMPLETELY useless. With mana spring always needing to be recast, and the pally buff lasting 30 minutes everywhere while MOVING, looks like this totem gets nerfed to the ground!
