eh to me a 2nd level spell should not be a battle ender and yeah blinding most thingsfor the whole fight pretty much does that.
A wizard's top level of spells-- regardless of what level the caster is-- is explicitly designed to be a game ender for his level.
When you're 1st level, sleep is a game ender.
When you're 3rd level, glitterdust or hideous laughter.
When you're 5th level, fireball or hold person or halt undead.
When you're 7th level, resilient sphere or confusion or fear.
etc.
This is all by design. A wizard's top spell level is his "wad" so to speak, and a wizard who blows his wad should rightly expect to dynamically alter the course of events.
