Please, don't patronize newcomers with nonsensical advice.

I'm expressing my opinion. You're the one spouting nonsense. Please read the thread about quick movement on the battlefield. It's been discussed many times! I discussed this topic with many respected players on ICQ. No one understands the nature of quick movement, so players share their observations. I understand that you don't recognize any authorities, that's why you're acting like this.
All your examples revolve around birds and garrisons, as if you haven't played other scenarios. What if we need to defeat 50-99 Marksmen guarding a swamp? By the time you reach them, they'll shoot you to pieces, but with quick movement, you'll suffer only minor losses. So, please be more polite...

P.S.: The birds died because of an incorrect assessment of quick movement, because the birds don't reach their destination, and with quick movement, there are no waiting times, and they are hit first.
