People play hardcore servers in CoD without minimap etc because less information allows for native skill and intuition to stand out more.

Sometimes the UI becomes a cushion and a crutch for players without skill, and puts them on an elevator to perfection without actually getting there on their own merits.

The game shouldn't just be a level grind. It should be a skill-grind instead. Practice makes perfect.

They need to be careful about how much information they give players and also how much skill-related stuff they decide to automate. Automating the entire combat system might be more convenient, but there is clearly a point at which the player behind the user interface is no longer even relevant.
