I would like to see TESO take it to the next level once again. Small DLC is fun and all but as a vet, I would love to see more. Some examples I can think of:
-New trials built for two player groups. Duo Dungeons are so much fun!
-An auction house for a more diverse economy (dont hate)
-Two new weapon types including UNARMED with their own unique skill lines
-Underwater adventuring with an all new sea elf campaign
-New incentives to just go out and explore, take down world bosses, and kill things such as new repeatable quests that give crafting mats and other useful things
-Randomly generated content so each time I accept the quest, it is something entirely new and engaging
-Stronger and more dangerous anchors where the NPC's actually try to take over the land after being summoned if the heroes do not try to stop them like in RIFT
-New weather and environmental changes while we play to change up the look and feel
