The interesting thing is that the three highest populated realms in Dwilight are those that border the West - Westgard; Astrum; and D'Hara. Below that, you have Westfold which is a bit further inland to the East. As has been said before, those realms are not really the problem. They're all clearly doing something right to maintain their player levels. In Westgard, we've managed to maintain the highest player density on Dwilight in spite of constantly being hammer by monsters and undead. Or perhaps partly because of it, since we probably attract people who enjoy the PvE gameplay.
The thing is that to obtain the 'desireable' player density over all of Dwilight is probably not achieveable if it involves losing 42 regions as Zakky mentioned the other day. Given the current flow of monsters from West to East that probably means losing 4.5 entire realms (some combination of Madina; D'Hara; Astrum; Westgard; or Avernus or Arnor or Fissoa) depending on how the monsters migrate.
We know that enforced player migrations due to realms being destroyed simply don't work. Please let's at least say we've learned that from the disasterous ice age experiment. Players will quit the island (and inevitably the game in a few cases), which will drive down the playerbase on the island, also driving down the player density. Then you need to lose more player controlled regions because your player density has gone down again. Rinse and repeat until you're left with just a small core of players who are left clinging to their devotion to the island. We saw exactly this happen on FEI following the ice age. We don't need to repeat old mistakes.
