I would like to see some domains when worshiping the Old Ones.
The most underrated comment by far. DnD has been flirting with Cthulhu since day one, even to the point of reprinting their "Demigods and Deities" when the flirtation became scandalous. The result is a lack of hard rules behind a Cthulhu pantheon. Without any licensing agreement between WotC and the Lovecraft estate there will be no explicit rules for Old Ones Domains. This is definitely something that needs house rules.
