The marauders you play with must be shocking cause the Mara/ pwertech we use destroys sorcs in dps.
If ur not healing in pve, or dps just for pvp re-roll cause that's about all sorcs are good for raid wise.
And as for the 5 percent within eachother then maybe sorcs would be useful in pve raids
You are bad. Go away.
Sorcs are perfectly viable for DPS in raids. I've cleared TFB HM and I do 1700 DPS on Writhing Horror and Dread Guard, for example. You can clear any available content with Sorc DPS. They are fine for raiding.
