I agree 100%!
I made sure I was first in line to pick up a copy so I could get the code and give TB a go. I'm glad I did, as I'm high on the feature and as a result, am higher on the game itself than I thought I'd be. When the patch comes out for 360 and I get a chance to tinker with sliders, etc, I can make a better decision.
If I do purchase it, I will also gladly donate my code to someone else.
EDIT: Also, it would have been nice for EA to maybe include a single slot, or trial activation of some sort (tied to your gamertag, perhaps) for people wanting to try this feature out before purchase. Maybe in the future...
