Lord Pendragon said:My PC just hit 16th level (14th-level clerical power) and my experience has been that if you're resorting to 1st and 2nd level spells for damage dealing, you're already in a heck of a lot of trouble and should be fleeing for your life.
At high levels, 1st and 2nd level spells are best used for buff and utility spells, preferably those you can cast outside of combat (like Resist Energy). For direct damage dealing, you should be using your high-end spell repertoire.
And that's why I suggested the Light spells, since they have a utility (Light) as well as the damage capability.
IME playing a 17th level wizard, there are are times where you don't want to do nothing in combat, but wasting a 5th or 6th level spell on what is essentially a mook is not worth the effort, and having a hanging effect that you can discharge without using untapped resources is nice.
