Dungeons & Dragons 5e playtests

Yeah, I'm still wracking my brain trying to sort out how the imperative to give the players casting options other than Vancian became "Here, have some spell points or something, except enjoy a smaller spell list, weaker power, and a horrible evil monster transformation when you run out of juice!" and "Here, pretend you're a Cleric, but your god is really a jerk instead of a god. Also those Wizards over there hate you and want to ruin everything you care about because while they had to study all day long, you got a tutor and some cliff-notes."

Would it have been so hard to just go "Hey some people like Vancian Wizards. Done. Now, lets build a AEDU caster and maybe a person that runs on Force of Will casting through hit-points or spell points or whatever." and be done with it? Did it really require months of work to come up with shitty ways to make Sorcerers and Warlock a worse option that Wizards?
