Bah even my sorceror, who I was the first to admit was sub optimal as he was my first and only arcane spellcaster, soon learned that his fireballs hardly ever got any use but that glitterdust effectively ended a number of supposedly tough encounters before they started.

I was still one of those who pumped the magic missile button far too often though, all too often the unerring ability to hit stuff was far too tempting.

Then again I was playing a sorceror with a wisdom score of 7 so I could be a sub optimal blaster person and call it roleplaying :)
