It's a neat idea but on my server Escha is incredibly crowded. There are not enough monsters to sustain everyone who wants to farm silt. No one wants to make a party to farm silt because more players lower the xp gained and less xp is less silt. Furthermore each of your current camps can be easily cleared (and kept empty) by a single well geared 119 player.
I think the easiest fix here would be to lower the respawn time of the enemies, but another fix might be to increase the level of the enemies we find. Things seem to cost a fair bit of silt and so I think many players will be farming Escha for quite a while.
