Level 1: Track, Animal Companion
Animal Companion: A beastmaster begins the game with an Animal companion. Animal companions are loyal allies in any battle. As your character gains experience, his or her animal companion will also grow in power (as though you were a druid).
Animal companions cannot be directly controlled by their master. They can be controlled with limited efficiency through vocal commands, and set to defensive or offensive behaviors as well as force them to enter stealth. They become more powerful as the master advances. The only penalty the master suffers from the animal companion's death is that they cannot summon the companion again until they have rested.
Second Animal Companion: At level 6, a beastmaster can have a second animal companion of the same type as their first companion out at the same time.
Heal Companions: At level 7, a beastmaster can heal her companions once every five minutes. This heals both of the animal companions for 10 times your class level.
Second Wind: At level 21, a beastmaster can call upon each animal companion an additional time per day.

Minimum level of 2+ (CR*3) to take the feat. So Mighty at 17+ and Advanced at 5+
Fey may get "adjusted" to where you get the benefits (skill points, DR, SR, etc) without the fey ties. Mythical or Legendary or some such flavor.
If these templates are allowed the base class will be tweaked further (possibly medium BAB completely to afford the two stronger pets). The templates may apply to different companions. Such as Companion 1 gets Mighty and Companion 2 gets Fey. That way they don't stack up the power but each offers some slightly different benefits (intelligent spotter and a more savage tank).
