In many of my monster hunters games, I offer three ways to build a character:

1) take a 400 point template and add a 200 point template from Sidekicks to it (total of 600 points)
2) build a 500 point character without using templates
3) build a 400 point character with access to RPM

I find the characters end up pretty balanced that way. The casters really don't feel like they are behind, but they don't feel like they're ahead either.
