Sure this could happen in some cases om Dwilight too but if you are in Sommerdale, you don't really care about Fissoa or Terran.
On EC and FEI, every realm matters.
Despite being in Terran, I regularly correspond and interact with people in Summerdale, Morek, LE, and Astrum. I think you underestimate the isolation on Dwilight. Join some guilds and a big religion (VE or SA).
I personally love how Dwilight feels like multiple continents in one continent.
