You can let the beast use your attack action instead of you doing it. Can also make OAs. I'd say that's worth something.I totally agree, but it seems like the beast gets very few options to actually do anything. Like I said, it all seems balanced, but a little stagnant on the battlefield when the beast doesn't do anything until you use an encounter power (and maybe not even then).

You can use your beast to play interference for the Wizard, for instance.
