So, let's start:
What do you think they'll be doing in this next game? Do you think they'll work that all rings are equal; will they work in amulets to serve as covenant items instead? Will they keep or alter the covenant system? Will they keep a PVP arena or will they focus more on the invading concept and make the community organize? What will they do with the spell casting system? and etc,etc. Let's not make this post a bunch of questions, discuss to your heart's content.
