Is it a good thing that the common folk don't know that sorcerers aren't interchangeable with wizards? This looks like a matter of taste to me: players who want sorcerers to stand out may find themselves dissatisfied with the current Sorcerer class and want the Favored Soul to be obviously something else, while players who find the current Sorcerer class sufficiently distinct from the Wizard class may wonder what the fuss is about.
I don't like any of the current Sorcerer subclasses. I think the only other class I can say that for is the ranger.
I think this is part of the driving force for me to get the FS where I want it.
These are both good ideas:
How about giving neither of the domain spells as "extra spells known," but giving both of them as "additions to the Sorcerer spell list for you?" That way, those spells are available to be known by the individual Favored Soul, but no individual Favored Soul has more spells known than other sorcerers.
No, dangit: I need to edit the above for sense. hang on. . . .
Edit to add: As mentioned upthread, many of the Cleric Domains contain Sorcerer spells. In light of that, maybe the Favored Soul needs to have its own, dedicated list of Sorcerer Domains that are made largely of spells from the Cleric spell list. If the Sorcerer gets as much emphasis as the Cleric in terms of having distinct spell lists (even if added to the Sorcerer list for the individual sorcerer), then the Sorcerer class might seem lessderivative of other classes.
Edit again: That was poorly worded, wasn't it? Of course if the Favored Soul gets Cleric spells, then it is derivative of the Cleric class to some extent; but what I should have said, I think, is that the Favored Soul would then have almost enough differentiaion by faith, one from another.
Individual choice is good, agreed.
This is what I was trying to get at in the UA Revised Classes thread. I said this:
I like a domain spell approach, but I don't see any reason why it has to be tied to the Cleric Domains. Just give the class a list of domains to choose from in a similar format to the Circle of the Land Druid. They can be separated by alignment (lawful spell group, chaotic spell group, etc), by concept (war, fey, healing, etc), or by deity (Bane, Mystra, Helm, etc), or anything else.
I also tend to find the sorcerer underwhelming. I have enough trouble trying to build one even in theory and be happy with the spells known. If I add cleric spells to the mix and try to make what I want from a spells known point of view I can't even get close, and that's if I only add 3 or so cleric spells. I think domains are a great way to do that. I realize that it probably does unbalance the FS in regards to other sorcerer subclasses, but I think that goes back to them being underwhelming as a class. Compared to other 5E classes I think the sorcerer lags behind and this would not overbalance it compared to them.
