Rest system is not problematic (you should rephrase that *YOU think its problematic* ). But instead rest system encourages a highly efficient play style and it highly discourages wastefulness and extravagance, it encourages people to devise strategies that they wouldn't have thought about otherwise......i guess you are a new generation player who is just simply not use to it.
Just try to work with it, it'll grow on you and then you won't like anything else.
As a side note, there was a recent RPG 'early access' release, called 'Darkest Dungeon', its still in development.....but it does bring some innovation in the concept of rest system, where it introduces only rest specific abilities where certain powerful buffs can be cast only while you are resting and every class has its own rest spells or abilities. I believe devs or modders may be able to learn something here. We may be able to make the rest system more interesting and add some strategical value to it, rather than just the replenishing the resources.
