Im new to the shaman class but my 4xElementals are lvl 66 atm. At one point I tried to see which totems stacked with each other, and I thought healing and mana totem did not stack. But i just read that they do stack. Can i get some clarification on which totems stack, and which dont? And with a Pally-4xShamans setup, how many totems of each should i have up?
