Here are some current development goals -
No Jedi (long-term development goal is to completely rescript unlock and skills to fit into the timeline)
No ADKs (implemented)
No 90% armor (implemented)
No player-created economic or PvE progression bottlenecks (in development)
Integration of post-14 content in a reasonable and canonical fashion
Increasing viability of playstyles and general replayability through diversity of equipment and location more than mechanical or mathematical changes
Adherence to and curation of Expanded Universe canon
Here are some systems in development -
A completely unique and organic instanced endgame dungeon and loot system
Space Stations, GCW sector control… really lots of space plans…
A separate PvP ‘path’ that separates it further from endgame PvE and crafting (partially implemented)
