No he won't. You should go protector or garment, not armor. If you have ice maxed and he's pure INT, you're naturally well balanced defence wise. I would chose protector up until 80 and then when you hit 9D switch to garment.
If your fire is maxed instead of cold, you should go protector because you'll have a high magical defence.
