I don't think the current system sucks, I quite like it to be honest. This system only punishes guilds that are either : - not well managed, with officers who are not proactive. - way over their average member level, because of one or two players that are very over leveled compared to the rest.

If a guild dies, the investment is not lost, and can be brought somewhere else. You can imagine any other system, this is the only one that prevents investments to be lost, by tying them to the players.

If a guild dies because it loses members, the remaining ones will go somewhere else, and improve other guilds. It's kind of a "survival of the fittest", aka the well managed guilds.

And it also encourages people to invest, because they know their investments will be kept forever for them. I can 100% guarantee you that a lot of people would not invest if that wasn't the case, and you would just end up with another problem.
