My brother plays sorcerer and he melts people pretty fast, there are no shiny 6k crits but he consistently does good damage. He can crit heals for 6k tho.
He kills the target often faster then my focus sentinel because he is ranged, and my sent has trouble hitting moving targets. And lastly sorcerers have excellent utility.
Their weakness is that they are squishy and that should not change really. Sorcerers are probably the best balanced class imo.
A sorc kills a target faster than a focus sent? Really now? I highely doubt that and I did not roll dps to be utility I rolled dps to dps and there other classes like sniper and marauader who has better dps and utility.
