Yeah, Niantic is so worried about making this an "active" game and forcing as much social interaction as possible that they've limited themselves terribly. Though on PVP, I don't see much to be excited about. With our current system, it may as well be Cookie Clicker PVP. There is no competitive or strategic play involved, just tap like mad and switch to type-advantageous mons every 5 seconds as your opponent does the same.
As for gyms: I just wanna see legendaries postable.
