I really love this feature. I woke up this morning to find:
Korch (large guild, small friend list) - 28/28 houses motivated, 8/8 supplies motivated, 5/6 cultural buildings polished, 2/2 special buildings motivated and 1/1 decos polished
Houndsmoor (no guild, med friends list) - 8/13 Houses mot, 4/7 supplies mot, 4/4 cult pol, 2/2 spec build mot & 4/8 decos polished
Cirgard (med, active guild, med friend list) - 10/10 houses mot, 10/10 supplies mot, 7/8 cult pol, 2/6 spec buildings mot & 7/11 decos polished
That is a huge increase on normal level's and although some decorations have been polished they are not targeted above any of the other items in terms of ratio's and the overall result is a huge uplift in motivations of the buildings and overall production. I can take a few decos being polished.
If you really hate your decs being polished just dont have current age decs - its not exactly difficult is it? My only issue is that the aid button tends to ignore my kings / queens and HOF's which is a little frustrating. As an active m/p er this also saves me ahuge amount of time personally which is great so overall very happy.
