Someone previously posted Cleansing does stack.
As in remove multiple debuffs in relation to the number of totems.

I personally have every Elemental drop a Totem of Wrath.
That's not part of my totem stomp macro, but on its own hotkey for the buff from ToW Glyph.
Similarly I have single keys for 4x Grounding, 4x Cleansing, 3x Healing + 1x Mana, 2x Healing + 1x Mana + 1x Cleansing, 4x Magma, 4x Searing... etc.
I have round robin keys for Fire Elemental, Earth Bind, Fire Nova, Tremor, Thunderstorm (not a totem).

I have three Totem Stomp macro's.
A PvE, a PvP and an AoE set.
PvP is:

F--- Totem of Wrath, Searing, Frost Resistance, Magma.
W-- Mana Spring, Fire Resistance, Cleansing, Healing Stream.
A--- Grounding, Grounding, Grounding, Grounding
E--- Tremor, Nothing, Nothing, Nothing.... but will manually stagger 4x Tremor.
