Easiest DPS specs for delves in your opinion?

root totem 2/3
kill 1/3 & knockback if others get too close
Hex 1/2
By then roots back (although you could talent to reset cd)

Also totemic > storm since you can dump more maelstrom into healing and lose less damage output. Pstorm is decent for a quick 5 maelstrom if you need to catchup heals
