Does anyone know what the back-end metrics are, and what they are actually used for? I suppose they would say it is so they can make better games in the future.
It is indeed to make the game better. Other things tracked (if you agree to provide anonymous gameplay data) are where people explore (hidden secrets nobody finds may be too well hidden), what skills are used (if everyone or noone uses particular skills they may need to be adjusted), class/race selections, dialogue choices, etc. There should be more detail about this before Early Access starts.
