From what I've read, it seems like multiclassing spellcasters will be more synergistic than they are in the tabletop. And with short rests being instant and with bards being able to give you MORE short rests in-between long rests, it seems like coffeelocks will be able to build up tons of spell slots. Sure, it won't be the theoretically infinite amount that you can get in the tabletop game, but it's going to be a lot.
For those unaware, warlock/sorcerer multiclasses can abuse sorcerers' flexible casting ability to convert spell slots into sorcery points and vice versa. Since warlocks regain spell slots on a short rest, you can convert warlock spell slots into sorcery points, which you then convert into "temporary" sorcerer spell slots, take a short rest, and repeat ad nauseum until you have way more slots that day than you could ever have normally. It's called the "coffeelock" because you could (at least originally) in the tabletop do 6 short rests in place of a long rest, which coffeelocks would spend converting spell slots instead of ever sleeping. Any sane DM puts an end to that asap, but video game programming is often not as rational as a human being is.
