I can't really speak to DoW/DoM leveling with leves, but with the exception of a rare few, you're better off spamming Collectibles to level your DoH. As a side benefit, you'll level your DoL at the same time from gathering all the materials for it. No joking, this is hands-down he best way I've found to level all DoH/DoL/omnicraft.
<edit> Having leves reward Venture Tokens would be pretty cool.
