IMO, the 5e warlock fluff is entirely geared toward playing a character that has a master. That is what the patron is. You have power because the patron gave it to you, not by any merit of your own, and your new class features as you level are also gifts from the being you swore yourself to. IDK, for me, the 4e warlock was closer to the right path with abstractly defined pacts. A fey pact might serve a powerful Fey, or might be one.
Might just be a few lines that rubbed me wrong, or something, but I definitely want at least a "patron" that is specifically not having one.
Either way, the game needs a dang binder! lol
