I think the problem is, some may disagree, is that when a good server is up usually they stay up for a long period of time, I understand this is one of our problems (not having enough good servers up), but wouldn't you rather have a bunch off good servers being on different days or different parts of the days? When we always have a server up like Pecon7s Boss Battles you tend to get bored of it after a while.
I also think its because our community is more teen than kid, so we have to during school time.
