I am hoping for 2 new specs, but who knows? This game already has a gigantic amount of classes compared to most MMOs, once you consider that each class in WoW has 2-4 specs that play quite differently. Specs are pretty much subclasses in how differently they function.
I’d hope more crafting fun stuff like clothes and mounts, it super annoys me that crafted gear becomes obsolete for actual ilvl so quickly, so you’re left with no reason to level the prof until you level the rep to get the pattern for the fun thing you want or the bag or the mount. I’d rather have it be actually useful to play, or be stuffed full of easily obtainable cosmetic stuffs. I’d take either one.
