If you're trading a ToB standard action for a Charger turn, I'd say that's it's about even. You're just shifting your spotlight to him.
Heck, you could claim the damage the charger does with WRT is yours effectively.
You could also spread it around, and let the party casters double cast.
You're not changing your turn for his. WRT is a swift action so you still get a full turn plus allowing him to go again.
