So, basically, the only totems that stack are the ones that actively do something, like searing, magma, elementals, tremor, cleansing etc?

I'm not able to find definitive answers on the web about mana spring stacking, but I'll go and do some testing to check it out.

Edit: I don't have a specific question - I'm just trying to understand totem mechanics so that I can mix and match things a little more effectively for my team.
