- There will be no runewords in Reaper of Souls. Or runes as knew them in Diablo II for that matter. At least for now
- The communication options, like chat and Battle.net, are a 'big focus' in Reaper of Souls
- There will not be a new Follower in the expansion, instead the current Followers will be expanded upon, with things like story-driven side-quests
- There is still nothing decided on PvP, but it doesn't seem it will come with Reaper of Souls' launch
- Adding Sockets will not be added and instead the Mystic should fill the hole of item customization
- Players will be able to chose which stat to reroll on an item. An example being given with Intelligence on a Barbarian legendary and selecting "that one stat"
- The only changes possibly coming to the Auction House are increasing the gold bid cap, but there are technical and legal difficulties to that
- Movement Speed will likely have its cap increased as it's being added to the stats affected by Paragon Points
- There will be no second class in the expansion
