The High Aldwin
This would be easy enough, but I doubt I would do it. Besides, Sorcerers can have a familiar if they want so I don't see the need for it.Give the Sorcerer a metamagic that makes the a spell not require concentration. Only one spell can benefit from that metamagic at a time.
Like...even if you don't use the proposed change to familiars, give sorcerers that thing I just said.
