Anyhow I had a tinker with the summoning rules and came up with the following. It should work out the same in character points, but not lock the summoner into having uber stats if the beast in question doesn't require it.
Let me know if I've broken it somehow
So the upshot is aThe summoned being will have a pool of points equal to the user’s level in the powe according to the following formula: (power x3) +4. Thus, a character with Summoning 3 would be able to summon a creature with Brawn 2 Agility 2 Mind 1 and 3 points in powers. The person using the power decides the exact allocation of stats and powers for the summoned being (with a maximum of 5 in each stat and a minimum of 1).
A summoned being cannot have the following powers: Healing, Duplication, Shape-Shifting, X-Ray Vision, ESP Telepathy, Mind,Control, Clairvoyance, or Summoning/Animation. The summoned creature can have advantages and disadvanatges. No more than 1 of each for every 2 levels of Summoning. Each advantage cost one point, while each disadvantage awards a point.
A summoned creature may have any of the following Advantages: Appeal, Fearless, Frightening Presence, Immortality, Instant Change, Non Sentience, Photographic Memory, Unliving.
A summoned creature may have any of the following Disadvantages: Involuntary Change, Susceptibility, Freak, Unskilled.
A summoned creature may also have a Weakness.
Level 1 Summoning can summon a 7 point Creature
Level 2 Summoning can summon a 10 point Creature
Level 3 Summoning can summon a 13 point Creature
Level 4 Summoning can summon a 16 point Creature
Level 5 Summoning can summon a 19 point Creature
