Also to note Short rests are limited between Long Rests now, not automatic anymore. So you have to be careful about how you use your spells. Quite vexing for a Warlock with limited spell slots and whose magic replenishes via short rests. Probably have to go as a Wizard, if I want to get the most out of a caster class.
If you get 2 short rests a day that is potentially 6 spells used a day, which feels accurate for how the warlock is supposed to be played. Being able to refresh all your spells without limit between each battle would have been broken.
