Worst Gym Experience EVER (List of Known Bugs)

So I've been fighting gyms like crazy for the past several hours after it went live. Aside from the excitement of feeding Pokemon, I must say: the game experience of battling is so terrible. In a word: much too lag.

There are so many bugs in the battle system, including but not limited to the following:

Dodge Bug: They still haven't fixed that! Quick Attack Bug: You use several quick attacks, and then suddenly your energy decreases and the HP of the opponent restores as if the quick attacks never happened. And the fact is, the server seems to ignore some of your quick attack requests for unknown reasons. Charge Attack Bug: When you finally overcome the Quick Attack Bug and manage to launch a Charge Attack, and the animation goes, and the HP of the opponent decreased, and then suddenly all is reversed as if nothing happened! But this time, after several seconds, it might re-register the damage and energy deduction correctly but it is late. I call it "Double Charge Attack Troll". Switch Bug: If you switch a Pokemon during a battle, first the desired Pokemon would be switched in, but then it'll be switched back to the original, and then finally the desired Pokemon would be switched in again. I call it "Double Switch Troll". And finally, when you defeat a gym, your screen will go black. Just when you think the game crashes, it returns to map soonafter. Troll again?

So basically, every operation available is buggy. What a nice job, Niantic! Did you hire the right people to construct the new gym? Seems like somebody has cut corners.
