1. Everyone wanted a long range weapon, I do too, but I can tolerate the hammer.
2. The Jade Sphere is HORRIBLE to use. It has absolutely no feeling when you use it (overloads feel powerful) and forces you to stay in one area which is crippling. There's absolutely nothing enjoyable about it to me whatsoever.
3. The augments forcing you to stand in a particular area and in a particular element and during a particular window (sphere is up) makes them useless for PvP.
4. For me the absolute worst part:
Make it an orb of special magic, not a piece of technology.
