The only reason I'd want the Wyvern back is because I thought it was kind of cool. I never noticed much in the way of "added" abilities when I played. Someone made the point about Dynamis and other EoG battles, your Wyvern would wipe after the first wave; so true but I believe that's why it went from a 2hour to a whenever you want to call with a decent 30 minute cool down, could be wrong. Otherwise, Wyverns really only helped a Drag when you ran solo, like the path companions in XI. I don't need a Wyvern in battle as a constant, a simple 2 hour would work IF it was worth using. If you gimp it then it's use less as the Wyverns didn't do THAT much to help or hinder the group. As I said earlier, it was an "OH SHIT" ability! LOL
