What happens (to your Water/Lightning Shield) when someone else places Earth Shield on your Shaman?

[Ualaa]

I know, as a Resto Shaman you can Earth Shield one target at a time.
If you place the Earth Shield on a different target, it removes the effect from the first target.

I also know, if you place a secondary Shield on yourself, it will remove your previous shield.

If your composition were multiple Resto Shaman, could each Water Shield themselves... and then Earth Shield a different Shaman, so they all end up with both Water and Earth Shield?

One elemental shield per character.

Earth shield stacks with lightning shield/water shield but a resto shaman cant have both active, but if you got 2 resto shamans both having water shield up and both buff each other earth shield then both shamans have earth and water shield up, works since mop

Really.
Cool.

So, if you have ten Resto Shaman...
