If recent discussions of the Warlock have made one thing clear, it's that a lot of people have a lot of very different experiences of the warlock. And that is largely due to the fact that the Warlock's spellcasting is so incredibly dependent on short rests. Using the standard "spell point equivalence" below (suggested in the DMG and used in sorcerers converting metamagic to slots) we can see just how much warlock experience is going to vary by whether the warlock is getting zero, one, two, or even more short rests per day. With no short rests the Pact Magic is worth about as much as an Eldritch Knight's casting, with one it's equivalent to a ranger or paladin, and with two it's pretty close to a full caster (ignoring other class features)
I'm glad to see my analysis from the warlock poll confirmed.
