There is absolutely no project in any industry where changing managers incites a one-year delay. That is simply not a thing.
Metro isn’t right either though. Initial balancing for 5v5 is not a one-year project. Not even close. Real balancing doesn’t even begin until the game is released and in the hands of millions of players who break it in ways that devs – even brilliant ones – can’t foresee.
The bottom line is that they think the game sucks and is nowhere near where they hoped it would be by this time.
