Our dots are actually much weaker then a warlock's, and our nukes, while big, take a lot of setup and a long time of un-interupted spell casting.
Right now we rely to heavily on the 1 or 2 comps that are decent for us, and even then, a warlock can do just as much and more.
At this moment in time, we're a weak version of an afflic lock with some arcane mage thrown in.
Our damage does not need to be fixed, but our role does. We're relying on outdated mechanics to get us by.
