5 level rule needs to be enforced once you start doing Horizon "tier" of Behest depending on the camp you go.

There is no reason why rank 24+ players should be allowed in a Horizon Behest.
There is no reason why rank 33+ players should be allowed in Nawana Mines Behest.
There is no reason why rank 45+ players should be allowed in BW Behest.

There needs to be a rank 50 camp open for level 45+ players, Mob levels should be adjusted to fit the 5 level rule if need be.

If you're 'that guy, or girl' joining Behest @ Camp Horizon level 24+ you're ruining everyones sp for no reason, please move to the next spot, I've seen rank 28's and 29's joining Behest @ Camp Horizon, ridiculous imo.
