I believe on the newer servers it is a good idea to remove some farms. Because early on everyone builds lvl 5s everywhere. Sure that works for the first couple weeks, but after that lvl10s are needed to feed armies and upgrade heroes.

If Evony did not clear out these NPCs I would not have but a few lvl 10s close to my cities. And in 2 cases NO lvl 10s within miles. (I randomed ported to these locations). Now that they have I can put in at least 8 lvl10s. It will help me immensely.

On the older servers though or super servers removal of NPCs is not cool. With upkeeps approaching and exceeding 60mil in war cities plus 15-30mil in regular cities, removal of these NPCs will result in quick refuge.

IMO you should clear inactive accounts and ANY account started AFTER the SS merger. These dead cities litter the servers, I do not care if they spent $5 the accounts are sitting dormant.

Just my 2 cents .
