Spawn Camping

In many games, the Respawn Time of all mobs is fixed, leading to players camping a high-level character near the spawn point so they can easily login just when they know the mob will respawn and kill it to farm the sweet drops.
This does not work in Runes of Magic, as the stated respawn times for all World Bosses is automatically varied by as much as plus or minus 33%. This way players cannot precisely predict when the Boss will respawn, just a window of time. This is to give all players a chance to catch the Boss mob.
