Hi,
I tested the DPS of the new spell singers. It is clearly insufficient to merit a mention as a DPS toon. I was playing with all the metamagics on and over 500 sonic spell power (pre metas). The SLAs hit for ~1000 in a non crit. The DoT SLA hits for 100-300 (crit included). It is pitiful damage when I compare it to what I am achieving with other builds.
