well, the thing youre asking for is kind of complex. u want that the game tracks :
Who did u played with, when did u played, how long did u played, what did u played, where (server) did u played.
thats hell alot information. and that for only one fight with one guy.. that is probably impossible to do. (well its probably possible, but needs much effort for a mostly notneeded feature.)
Here are the things that would actually make this impossible:
1. Not having the data(we have the data)
2. Not having access to the data(we have access to the data)
3. Not being able to use the data(we can use the data)
P.S. it takes longer to load this page than it does to look up your last 2000 games
