New Features
What I Want: Some sort of long-term multiplayer survival island you can return to and resume surviving in. Another try at rogue-likes and at warfronts (except warfronts against lore enemies, not the other faction). A better version of Island Expeditions crossed with Argus invasion points. Zone invasions like in Legion but around the world. RPG-style advancement systems. Turn-based JRPG style mini-game dungeons (basically an evolved version of pet battles dungeons).
What I'll Get: Nothing that's really new probably.
