If my KD is high I’m not dying but the enemy is. If I’m a DPS I’m doing my job, If I’m not dead that means I’m very likely with my team or I’d get caught out a lot on my own. Getting a lot of kills and very few deaths in teamfights is really good.
It’s called Gosu.AI btw. The bot for Dota 2.
And one major difference about the review videos for Dota is it’s actually like a spectator version of the game. You can move around and view stats at any moment during the recording.
