Gameplay review?

Just out of curiosity,

Is there a place or a higher level player who is willing to look over a replay of a game that you played, and give some tips on what could have been done better?

I sometimes have difficulty understanding what caused us to lose a game.

I could of course figure out the obvious stuff like 'we had no tank' etc, but there are often games where I feel like the team is doing good, but in the end we just couldn't seem to find the right fights and lost.

It would be great to get some feedback from better players.

Thanks.
