A sorcerer can be quite a good blaster. Generally, its not considered effective for Wizards to blast because its more effective for them to leave all the enemies naked, hogtied and upsidedown for the fighter to coup-de grace.

A sorcerer has the spell slots to blast, if he wants to. Generally, this is even the sorcerer's archetypical role in combat: "casts the spells that makes the mans fall down."


There's a variant sorcerer that gets better metamagic, but again, not in core. I personally don't take much metamagic as a sorcerer, no.
