I went to the Sycrus Tower twice today with my new Viper. The first group couldn't defeat the second to last boss. Instead of repeating the game, this group was disbanded. After a total of one hour, I waited another 30 minutes in the alliance raid. The second to last boss froze as expected, but without the necessary ice block that protects against his strongest attack. Another wipe and another hour wasted unnecessarily by disbanding the group.
Absolute botch by Square Enix: How can it be that old, absolutely safe content is suddenly buggy?
