Nexon, forget about the estate, or even a 2nd estate. What we need in highers ages is more oil production.
Can we please have a Texas-style plantation of oil wells, something the size of our TC, with 9 additional oils wells?
Oh, and at a reasonable cost, say $29.99?
I think we need more refineries. Funny how gold and food which are trivial (gold much more so) are spread between 4 mills/markets and 8 farms/caravans. While the all-important oil resource is only sequestered in 1 refinery and 5 wells. It's reduced a large part of the game to using the overpowered wall miners (the three level 15 wall sections they can blow up in one attack cost more than upgrading the miners from gunpowder to global) and raiders with one shooter to make your entire army of idiot defenders chase one guy. It's a bit crap.
The last thing we need is more refineries. It just creates more attack vectors for raiders. There is a reason most Atomic players give up on trying to protect gold and food, building all their defenses around the refinery instead. Guarding all these resource storage buildings doesn't scale.
See i made this suggestion a while back and i didnt have many takers on it. 2 refineries would reduce the quick oil raiding attacks plus no need to nerf certain troops because they would last as long with oil be so spread out like that.
