The top 10 list will drop significantly in average points, back to 5000-15000 authority towns. The current top 10 towns will either lose most of their boundaries or will be pernament poopclaimed (which is fairly easy to achieve now).
This patch itself is fairly good, boundaries and other town assets should be protected. I have seen great suggestions from i.e. Pilgrim (he came up with a more balanced and yet intensive way to deal with boundary stones months ago) sadly they have picked the easy way and just made them destroyable without any game around. The only thing which really bothers me is that they have yet again implemented changes without a fair warning, it should had been properly announced so that the people had some time adjust in advance (as they have done with previous things, such as scents and flags etc).
There was still a 2nd line of security in placement, which was the waste-claim. Would it be known, not even far in advance they would still have a day to fix it. I feel sorry for the people that actually noticed the waste-claim and thought to be safe to see their town removed later.
I feel stupid for not realising the mistake, Whiskers was the first victim in my knowledge that had this mechanic used against him.
