Two crafting please don't [censored] it up! Star Wars Galaxies had the best crafting system ever created of any game. There is simply no other crafting system that has matched it. For the love Mehrune please take some ideas from SWG!
Pvp, look at Dark Age of Camelot. DaoC had some of the best pvp I've ever experienced and took real teamwork. Nowadays I go into a battleground in WoW or a Warzone in Old Republic and go off to do the objective myself with enough expertise in DaoC this wasn't gonna happen. I had to plan carefully and as group fill a role. It was great and since this will have 3 factions I would also like to see what Bethesda can accomplish. Guild Wars 2 beta also has some excellent WvWvW and deserves to be looked at.
Those are my big 3 that this MMO must have for me to subscribe. How about you guys?
