If they disable short rests on Tactician then they totally gimp Warlocks , Monks and Bards.
Warlocks specifically will only have 2 spells a day and then have to long rest. Not a good design and makes them many times weaker than Sorcs and Wizards.
The opposite is true if they make long rests harder to achieve and short rests remain the same- then bards , warlocks and monks will be mandatory for a good party and wizzards ,clerics , sorcs etc will be gimped .
The problem is warlocks, bards and monks are already strong, sure, removing short rests would gimp them but they would still be playable, the true kings of that scenario would be fighters, since they can just can keep on going, all they need is HP.
But at the very least a middle ground would be removing one short rest. Also, long resting doesn't become a problem unless Larian would introduce some type limitation to it, early game supplies are nuisance but quickly you get showered by all kinds of foods...
At the very least Larian should introduce the no-resting red zone in more places, and make it so if you try to game the system by going out of it's boundaries to rest, it would cause some quests to fail. Introducing some type of difficulty and consequence.
