Keep in mind that every addition to the game changes it's economy, and since FoE is a competitive game, every new, "optional" content has an impact on you, no matter if you're interested in it or not.
Let's say you are fighting for position with player x, and you are even in terms of strength. Then boom - castle system is out, and in the same day your opponent has it maxed out, immediately gaining significant advantage. You want to have the same thing he has, so you want to put an effort, and climb your way up to lvl 15. Then you hit the daily limits wall. Your opponent didn't have it, he could buy his way up to the maximum in the first hour, but you need to wait ...couple years. So, you are left with the option to buy it, leave it, or being bottlenecked by unreasonable limitations.
Seriously though, the kinder garden attitude of "don't like it = don't play it", and calling players who have some negative feedback spoiled is not amusing... This is a place to write such things... Peace.
