One way to help improve yourself in M+

Most people think of details as a damage meter but it's really a lot more capable than that. It has two modes that are really helpful for improving yourself. One is "avoidable damage taken", which is exactly what it sounds like. The other is " damage taken", which is all damage (obviously).

You can aim to be at the bottom of both of these meters. Ideally your avoidable damage taken is zero. In terms of all damage taken, proper use of defensives will lower this number. Then if you hover over the bar, gives you a breakdown of what ability did the most damage. Myself, this has helped me realize that I struggle a lot with the wind-ups in floodgate. Not sure how to fix that yet, but at least I know what to work on.
