Totems are now on short duration and some with a cooldown. (Totem change in MoP)
I know some of the reason to support the removal by blizzard was, they wanted dispels to be more methodical and mean something when you did them.
However,
Monks have this ability, which bares similarity

To a lesser extent Priest have this

Does a cleansing totem on a 3 or 5 minute cool down that removes negative effects from x amount party/ raid members, that far out of reality or beyond the realm of possibility?
Is there some justification to bring it back?
People often ask me, if it be in trade chat or guild chat. Is such a thing even possible? ...and I say yes, yes it is.
