Everything has problems, it's just that different people value different things.
- The current ward system is hard to scale as player count increases
- If the amount of wards is made high enough, everyone will move to medium or large houses, resulting in ghost wards with a lot of empty small plots
- Instanced housing doesn't have neighbors
- Vacated plots being immediately available for purchase allows flipping
- The current timer system requires insane time investment to get your first house on a crowded server
- In a lottery system a player is unable to obtain advantage over others
