If you're considering the God-Machine rules (which are ~3/5ths of the Chronicles of Darkness rules, missing the crafting/organization/planning rules, investigation and clue-finding, the new chase architecture, and some last-minute polish) almost all of Changeling 2E is in open playtest here:
http://forum.theonyxpath.com/f...en-development-blogs! Chronicles in Darkness in general tend to be smoother, stronger, and more I guess "flavor-packed" in terms of theme and mood, so that might help down the balance gap a little.
Onyx Path is still taking feedback and it'd be a help if you were willing to consider it, maybe formalize a request for players to send in their experiences from time to time.
If you're dead-set against it I'd still be interested. Changeling and Mage are pretty popular individually.
