id argue vod reviewing deaths is wrong as well
cuz when you are looking at your deaths in isolation its a lot of "i shouldve backed out here" or "i couldve played safer" when most like ur death is not the biggest mistake that happened that round, a death can even be a good high round conversion play.
whats way better is if you're vod reviewing yourself mostly focus on looking for mechanical weaknesses and catching yourself autopiloting, and then focus on those mechanical weaknesses in deathmatch
a lot of gamesense can be fixed from playing more aggressive and taking aggressive timings to get a better feel for those timings
looking for general macro mistakes is pointless unless you're higher immo pushing for radiant, external coaches geenerally help way more with macro
