I'm assuming that it's probably similar on other servers, but on Coeurl, I think a grand total of 20 of the housing plots in Shirogane went to FCs. The overwhelming majority went to individual players, with probably half of those players intending to flip the house for a profit.
Given that FCs routinely band together to raise money for things like houses, and given that such an investment represents more than just the time and effort of a single individual, you'd think SE would realize this and give FCs the first shot at housing. Maybe even open a few new wards in all the housing areas just for FCs. Maybe, I dunno, have some GMs that are sitting around watching for people flipping houses and banning them immediately, instead of hoping people will report them instead of caving in to their demands. But I don't think any of that's going to happen. It's hard to build a sense of community in a game when the gaming communities in the game are given such a low priority compared to those who want to abuse their fellow gamers.
