Ok guys so the trick for doing instances with 5x shamans is Earth Elemental Totem that you will get at lvl 66. Actually is really cool because you have 5 mini tanks that don't need heal, so the rest of the group is dps... 5dpss, it was quick.
yep, yep, I made AC and MT and I'm so glad :D
My mistake, i said 64 instead of 66 to get the elemental earths. But im kinda confused, cause i had the idea i got them at 64, and grinded Blood Furnace with them...wth...
Earth Elementals are part of the key to success. Once u have elemental fire (at 68 if im not mistaken), u can mix 2 of them with 5 ele earths and have a nice mix.
I never bothered much healing the tanks, cause the dps is so fast that the boss dies before the elemental, so, from now on ull have a much easier life.
