Shaman Totem usage?

[Talos]

Some totems still 'stack' in some sort of way:

4x grounding totems -> 4 different spells being absorbed before having to replant them
4x healing or mana totem -> in the past only healing stacked, but right now also the mana totems stack. use 2x healing/2x mana or 4x one of them for extra effort (in pvp with 4 shammies i use 4x healing, in pve with my pally tank i use 4x mana).
4x searing/magma totem (or 1x ToW 3x searing/magma) for extra dps (or as Ualaa mentioned 4x ToW totems if they are glyphed for the extra ToW +% that is only on cast on the player laying down ToW)

i was under the impression that healing totems stack, but mana does not. also, mana totems do not stack with blessing of wisdom (if you have a pally).
