You say you blame yourself and your team more than Tarkin (in the game). But I think that's the issue tbh. If you "blame" your opponent for a good play, that brings people up. He circumvented the entire team to do that. Twice.

There isn't a ground player assigned to your backline. Nobody is actively thinking to themselves "alright, I need to hold this front, take these mex, and screen around my air player's factory for gremlins". Getting them to bail you out isn't something you should take for granted when you get hit from an unexpected angle. Rather than blame, it should be Tarkin's insightful exploit of the weakness that should be celebrated.
