Well since this suggestion won't lead to a higher population server, I guess the next focus would be how to get more people in the wild. MIGHTY RED DRAGON!
I understand your enthusiasm about the wild but not everyone likes or wants to pk. I support those that do and I hope they enjoy the game however I don't support adding content to the wild with the specific purpose of making players who do not want to pk go into the wild because that is the only place said monsters spawn. I offer a compromise and say yes put them easily available in lvl 50 wilderness but also make a new dungeon requiring high skills to access and possibly even an extremely cumbersome/difficult quest. This would be fair to the skillers and pkers and would still give people an opportunity to farm outside wild or without high lvl skills.
