It is a bad idea to significantly increase the amount of rest fights.
The game is balanced for 2-3 fights to rest which is good.
Thanks to this, we can have more interesting and difficult fights. If the game was balanced for a larger number of encounters, they would have to be much simpler and it would end up with junk mobs that pose a minimal threat like in WoTR.
Thank for the dubious pleasure of playing such fights in TB.
In the end it will only end up with a more boring game where you spam cantrips most of the time.
