Hi Themarten,
No, I'm not at all insulted. I just find it interesting that players come along and play for a week or a few months and say that "It needs to be looked at by the devs, and changes made promptly." Having said that, I always like to see new suggestions and there is always the possibility that they might be implemented. I think it is reasonable for other members of the forum to comment on those ideas and suggest why / how they might / might not work.
Yes, the developers can change whatever the company asks them to change. This is not the first time a shield cooldown has been suggested and so my best guess is that it is not something the company is interested in changing. I don't think that it's a waste of my time to tell you so although perhaps "never" was not a good choice.
You have asked me to be constructive and post links to strategies. I suggest that you look through the Fan Guides section of the forum as there are many good strategies there. If there is something specific you would like to know about, you could ask in General Questions.
You have asked me to think and I would ask you to do the same in return. You seem to be suggesting that the shamans should play some role in Shields and Relocations. Can you elaborate on how this might actually be implemented in the game? I am also curious where these attacks "every 1-2 seconds, dozens of time in a short time frame" are likely to come from?
As I said in my earlier post, towns can already sit unshielded for long periods in one place and attack tiles or towns. They can simply make sure that all of their troops are on the march either to attack or to hide behind someone else's shield. Sure they get attacked every now and then but if they lose troops they can heal them and send them out again. They would be attacked even less if a cooldown was in place because the potential attackers could then have to defend against attacks on their towns.
