Good morning folks,
Just a couple quick notes, since this is obviously a pretty sore topic with some of you. As posted above, this is NOT an exploit (thank you Silenteye7 for pointing out Kalvan's post.) That said, it's perfectly fine to suggest changes to mechanics that aren't considered exploitative. Feel free to discuss game balance and mechanics changes to your hearts content, knowing that the developers do read through your concerns and factor them in whenever possible.
Please keep it civil, and focus on the perceived flaws in the mechanics as well as possible improvements you'd like to see. Together we can make siege warfare as fun and fair as possible for everyone.
Thank you for your help, and have a great day!
