While i whole heartly hate the system we have right now with the buying (even thought i finaly was able to get a small plot) the fact that single players can get a large plot is a non issue for me (and i never plan to have one ) yes there are FC´s that would actively use a large plot but most i saw were pretty barren and even ours is often pretty empty even when we have 20+ people online so why should only FC´s have their vanity plot?
Best FC Houses i saw were mostly small plots with full guild appartments where the lead would creat RP fitting rooms with their mains/alts
