Would you like an in-game parser?

[Frowny]

Also, another thing to take into consideration, a lot of these parsers come with extra features that make it insanely helpful to players. Things like the ability to search through your battlelog and see exactly where someone messed up and how. Timers, for fights as well as personal skills for better recognition. While being able to see your damage and other teammates as well, parsers outside the game will always be a thing as long as they are not provided in the game itself.

I think the log thing is more if you upload to a certain site (can make the log private). I myself haven't used that bit, but it is indeed nice to analyze a static and point out errors for the next run.
