My players don't like the 5MWD, but they like having interesting things to do every round of combat. In 4E this was pretty easily accomplished, since even At-Wills did a little something special.
But in pure attrition models, conserving your resources often means not doing something interesting.
Of course, the DM makes the fights more interesting by adding secondary objectives, interesting terrain, and rewarding skill checks. But every time a turn is spent using ONLY a basic attack or pure damage cantrip, something is going wrong.
In 5E, a long rest is often the best way to get back to doing interesting things.
