It almost feels as if they are giving up on the game because they shot themselves in the foot back in August when they attempted to make those changes to make it harder for beginners and f2p players so that they can't progress without spending $. I bet they must have lost a big trunk of paying players also. I used to only get the lowest tier of ranking rewards in events and now I am top 400-500 and I don't spend a dime.
It seems like they realized even when they reverted the changes the damage has been done and players lost and now they don't bother trying as evidenced in the new modes/features that never came. Also, they used to at least give compensation in the form of more silver coins in tower chest if they messed up the events, now they are just like oh we fixed the glitch, you are out of luck that you couldn't progress for 12hours because of our programmers' incomptence. They don't care anymore.
