Volcanic Fissure + Ancestral Totem is very bugged

If you selfcast Fissures you can use stampede or sunder to trigger said Fissures.
If you use totems to cast the fissures you cannot explode said Fissures
If you cast fissures your totems cannot explode fissures
if your totems cast fissures and use seismic/sunder to explode them they cannot explode the fissures.
The ONLY way it works is if new fissures frm the totems trigger the old fissures eventho the skill states that you need to use a different slam.
This mechanic should work with totems since you can also use seismic totem to expldode jagged grounds you place. But it doesnt.

Confirming this one, getting the same problem.

Yep. Either the skill text needs to explicitly state that it doesn't work with totems, or this should be fixed IMO.

I also had the plan to make a support totem and was sad to find that it didnt' work.

I just got to unlock the Ancestral Totem and i had planned to use it for this but seems this still doesn't work! Will this get fixed or is it supposed to be like this?

Whats the best alternative for this usage? Earthshatter on Totem? or Sunder? or just forget about it?

Bump. Been looking around to see where this discussion was happening. Definitely a problem and have tested all the options OP tried. This effectively limits the combo potential of maces dramatically and it's very disappointing. Hopeful it will be fixed!
