Main draw for some is the cheesey way of converting all of your Warlock slots into Sorcery points, and then converting those points into Sorcerer spell slots, and then taking a short rest, gaining back all Warlock Slots.
And repeating that 3 more times while the rest of your party sleeps because you are a trancing elf that only needed 4 hours of rest to not take ranks of exhaustion.
The maximum number of Sorcery points you can have is equal to your Sorcerer level, when converting a spell slot into points, you gain points equal to the level of the slot.
At 3rd level Warlock, you can turn your two level 2 slots into a total of 4 Sorcery points. Enough to create 2 1st level slots. If you can get in 3 short rests before the adventuring day starts, that's 8 extra 1st level slots to begin your day with, and you can do this as soon as Sorcer 2, Warlock 3. So a 5th level Drow can begin each day with 11+ level 1 slots.
But the full Sorcerer in the group is unimpressed by your endless stream of magic missiles, because he can cast Fireball, and cantrips jump up at level 5 to be nearly as good as level 1 spells.
If I was your DM I would tell you you can't rest again because you aren't tired, and you aren't going to be tired until I say you are.
