Hey...don't get discouraged. I know it hurts when matches like this happen, trust me, I've been there before
Whatever happened during the match, you can't change it. I know it may not be right, and it may not be what you planned on doing during the match, but things happen in matches that noone has control over. Maybe the opposing alliance did something that your alliance didn't expect, and it caused them to act differently, or maybe it was something else. I dont know, noone really knows. But most importantly, its in the past and it can't be changed.
But you can learn from it. You can learn tomorrow by playing matches differently, you can learn how to build differently for next season...competition is the best learning experience of them all. And, don't let one bad match get you down. You have many years ahead, many more games, and many more matches. The best you can do is to keep your spirit up in these trying times.
And finally, don't you dare tell me that rookie teams don't get into the finals. They do, I've seen it....and the competition isn't over yet...you could get picked
And there's always the offseason! Stuff that happens there yields huge bragging rights.
So...don't give up hope. And if you want to vent, feel free to pm me personally, I'd be happy to listen.
