I have been strongly considering to pick up multi boxing soon after being burnt out of playing solo on a mediocre realm, I would do five shaman if I did and would pursue 5v5 arena. In regard to race I see orc picked often which is for the stun resist and blood fury? The trolls racial seems that it would be of good use in arena since your bursting and the 10-30% speed increase would help but I don't know if it outweighs the orc racials. I was very curious to if chain lightning could take out two enemies at once if they were close enough from a NS+EM+trinketed CL? It seems this should be possible with five shaman but can it be done with less? Lastly is it more beneficial to take a healer as your fifth or is it purely for social purposes? Thanks in advance!
