Choosing Elyos or Asmodian in Aion 2 has little effect on gameplay: both factions have access to the same classes and content. The main difference is cosmetic, so the choice matters chiefly if you prefer one faction’s appearance.

Players can still fight members of the opposing faction in PvP whichever side they choose. The guide advises paying closer attention to class selection, which it says has a greater impact on both PvE and PvP.
