It is not fine, because the same people (not going to mention names) keep making a new guild every few months just to get another reward. This idea would encourage them to take a guild farther rather than creating a new guild.

Currently, if a guild gets 5,000 hours, they get two hats. But a lot of people just make new guilds, because they can just create 5 guilds, getting 1,000 hours each to get 5 hats. Implementing this idea would make it pointless to recycle a guild every few months and more guilds would get to 5k rather than stopping at 1.
