I use a res macro now on all of my resers

/cast [target=playertarget,dead,exists,help][target=ArenaPartner,dead,exists,help][target=shaman1,dead,exists,help][target=shaman2,dead,exists,help][target=shaman3,dead,exists,help] Ancestral Spirit

When someone dies. i just hit that button which is bound to the same key on all my shamans (ie. 9) then they all try to res. It's worked a couple of times for me.

The first condition set [target=playertarget] lets me manually select a body to res, that way if i'm out and about and see someone get wasted I can just click his body and still hit my '9' button to res them. In arena this should work everytime with the [...,help] conditional to ensure it's not stuck with an error trying to res someone you killed.

happy res'ing
