So I have a 5 shaman team and we are all level 63. I tried to complete Blood Furnance and can't get past the 2nd boss. I find myself lossing 2 guys after the 3rd gate opens. I tried backing everyone up to a wall too minamize the effects of the knock back. Is there any tricks to getting through the gate event? It was pretty frustrating last night I thought I was going to cruse through the whole instance.

I sent myself some spell damage food and have some spell damage exilirs from a quest. Should boost my damage by ~50 spell damage.

Any hints/tips will be appreciated
