Sometimes you wanna go somewhere and not do any fights, sometimes you wanna grind and wanna do fights back to back. In both of those cases having physical enemies out in the overworld running around ready to aggro you is worse than random encounters with a rate control. If you wanna go somewhere you are forced to either fight or somehow avoid all the enemies, and if you wanna grind not only do you have to walk to each enemy's location but once you clear an area you gotta zone in and out of it to get the enemies to respawn and get another fight. Jrpgs have evolved around random encounters so they fit em if they allow you an easy and good way of managing them.Nah, some mechanics are shit like random battles, which literally only ever existed in the 1st place due to hardware limitations. They make the world feel lifeless (you see nothing in the game world) and they disincentivize exploration. Having to go into the options to constantly adjust it like Bravely Default just proves it's a bad mechanic. QTEs are hardly even a mechanic, it's just a game telling you to press buttons at a certain time instead of having normal gameplay flow of the player deducing for themselves what buttons to push and at what time.
