Even if you prepare one spell per slot, a la Vance, you'll wind up with about an hour and a half of preparation if you want to customize everything (EDIT: I forgot to confirm, but that's actually too many spells prepared. The point still holds though). That's not always possible, especially on an adventure with time pressure - when a long rest absolutely cannot be longer than 8 hours.   It also matters more if you're using the variant "Epic Heroism / Gritty Heroism" rules from the DMG, which redefine the length of a short or long rest, but leave the length of time spent preparing spells alone. Or if you're a multiclassed character - you need to track the time spent preparing spells separately.   Also, while a wizard's spell slots refresh, in 5e, those are separate from the act of preparing spells. Presumably, rest merely recharges a wizard's reserves of arcane energy - hard study is what lets him prepare the spells, in effect memorizing how to direct that energy and setting up the magical scaffolds (or, if you prefer, macros) needed to cast the spells at a moment's notice. The slots reflect the actual energy, which is directed outward during spellcasting. (This interpretation also explains why a wizard / cleric shares spell slots but uses different prep systems.)

With that being said however, the wording is slightly ambiguous and has wiggle room in terms of interpretation. Most DMs (including myself) simply rule that you only spend time preparing the new spells. YMMV.   FYI, spells are not prepared during a long rest, but after.

#10 EzechielDantan Jan 21, 2015 1:40:37	I suppose it would have been easier to have a wizard simply renew his list after a long rest. The present rules seem to be a bit out of place in this edition where fiddling with components and the like is minimized.
