Orders
I feel that A-net made a point of stepping away from diverging stories.
Having diverging stories overall means a lot more work for a similar amount of gameplay. Story quality is usually better when there are fewer choices, or if the choices don’t impact as much. The choices in HoT are generally quite simple in that they don’t take you into another instance (like in PS), but often give you different dialogues/NPC interactions and another path around the same instance.
I would love to see some more gameplay involving the orders and the choices we made when choosing our selected orders.
I wouldn’t expect a whole storyline or an expansions worth tho. Maybe just a new daily mission system for them or something. Think of guild missions such as the Treks, Bounty’s etc just applied to the orders.
It could be a fun new small system that could bring something new to the game and give us something other to do to help as filler content until more expansions, living story is here.
