And increasing their mana cost would make them suck.
Flame Tongue does the most damage of the level 1 spells at the 25 power cap. At, say, 100 power, it would average 17 damage per hit. (although shock would benefit the most from this, due to double-zaps)
Airstrike, I think, does the least damage of the level 4 spells. At 100 power, it averages over 19 damage per hit. Throw Icicle, by comparison, averages over 31 damage per hit.
If we're imagining this ego being used to offer more variety for conjuration usage -- i.e. allowing low-level conjuration spam to scale up to the mid and late game -- then I think adding 2 MP to the mana cost would be too much... unless you really were imagining keeping the low-level spells strictly inferior to mid-level spells. Heck, 1 MP might already be too much.
