Yes, I'm not too sure about Vancian casting either, and wished they'd gone the 5e route in this area.
Honestly? I don't, this approach may be less streamlined but you get way more design space in how casters work, more differentiation in their playstyles, and it helps to balance the power and versatility of magic in these games.
It's less of a flaw in 2e, and more of an important mechanic 5e players won't be used to.
