I hope this game doesn't follow WoW's expansion routine.

I really love how people try to 'debunk' something, make a fancy list, and then include that ARR 'stole' the idea of the FATE system... from Rift. FFS! no. no. no. (well, at least they didn't say GW2. hm)

It's not called stealing when a game, or movie, or music album, uses designs that are critically acclaimed. There's no such thing as a copyright on game features —merely on the underlying proprietary code, as far as professional coders can avoid using comparable languages and algorithms.

Game design is a very iterative process, that's just the way it is. Here's a commentary on this notion by TotalBiscuit (from 0:38 to 3:48) that I found quite spot-on.

As far as 'public quests' are concerned, it was coined by Warhammer I think, and probably taken to the next level by Rift and GW2, before ARR—and in my humble opinion, ARR's take on it through the FATE system just isn't very good compared to what's been done in other games. Given the huge criticism made by players on FATE's, I think it would be smart for SE to redesign this feature in order to make it more engaging and less boring, bluntly put (see: backlash over the Lightning event for instance).

Note: I've completed my previous post (a projection of a typical ARR's expansion based on existing similarities with WoW's design), to make the list more comprehensive and hopefully free of judgemental takes.
