Meanwhile to me the difference between "I have a wellspring of power that I can draw on to cast spells" (sorcerer) and "I have a wellspring of power I can draw on to cast spells that comes from book learning" (wizard) is that wizard is clearly a subclass of sorcerer.To me at least, the difference between "I made a deal with an entity from Beyond." [Warlock] and "My ancestor made a deal with an entity from Beyond, and now it runs in the family." [Sorcerer] is the conceptual difference between two sub-classes, not the conceptual difference between two different classes. Sorcerer and Warlock should be combined. Leave Wizard as it is.
Meanwhile "my ancestor made a deal with an entity from beyond" doesn't particularly sum up the sorcerer. "I'm a seventh son of a seventh son" is also a sorcerer as is "I spent seven years in the shadowfell and it seeped into my bones so I manipulate shadow" and "I was struck by lightning by the century storm and a part of it is now part of me" and far far more that involves neither bloodlines nor deals. Sorcerer is more than fine as is in D&D - please stop trying to dismember it in order to get it to fit into a small box.
