When I get to play at all instead of DM I almost always wind up playing the Arcaner since after all these years no one else has ever really figured out how it works. At low levels, I absolutely use Burning Hands.
Between lvls 2-8 it has better damage than MM, and has the ability to deal that damage to a few enemies in whole, rather than splitting it between a few as with higher level magic missile. It does allow a reflex save, but typically low level monsters have high Fort, low Ref & Will saves, so I'm never all that concerned. On the whole, I actually prefer it to MM.
Evilly enough, since my players don't "bother" with arcane casters all that often, I will occasionally be mean & pull an invis + burning hands on them. They have such a lovely tendency to clump together, and it gets 'em back for all the times they left my caster characters to fend for himself in melee.
