Lylay, since it is not a bug, and maybe only an abuse that can be exploited only in very rare cases i think is not a high priority for game designers. I'm following the development of this travian kingdom game since the very first beta server (3 years ago? i dont remember) and changes happen very slowly, even after many month. Asking after a week if an idea will be implemented or try to understand what game designers are going to do or if they are working about it, is not ''good education'' for my standards in a game forum and 99% useless after players were warned that this thread's idea is already forwarded to game center.
I learned to keep an eye on Announcement section often, and stop. You cant expect that a game designer reply you here only beacuse you aked him, i'd be surprised cause usually it never happens in the most of idea-suggestions.
The logics behind my words are '' if everyone did it philosophy'' ''wait and hope''... and many years experience on travian forums. Probably was this that Mayo and Renuo wanted to say.
In the case you are waiting an answer or fix from game designers in order to plan your next off op with a zerg tactic or not in your servers... i suggest you to change strategy meanwhile, it could take some time, as always, for this kind of things!
