The more pips you have when you cast the more health and the higher level spells the minion apparently has available to it. I think many are upset that only the death minion is allowed to be cast at stronger levels of strength. I personally favor all minions of every type to be cast as such, and for the strength of minions to also take into account and be adjusted by the level of the caster. Additionally I favor myth school to be able to cast minions as if they belonged to every school, that is to say their power pips counts as two pips regardless of the minion's school that myth is trying to cast.
I think minions were designed a specific way for a specific reason. For example:
The life minion, the sprite, should not be able to cast like a death minion. It can heal but has somewhat lowish health, if you could make it stronger than i think it would be unfair. It would be just like another life wizard.
So people don't be upset, be happy you get the chance to have a minion at all!

Are you willing to wait until level 28 to receive your minion?
