CWKPQ!

Since CWKPQ is being re-released as it used to be, it'll be really easy for now, but in the patch notes it does say that this is just part 1 of the release (or something to that effect) so it might get beefed up a bit later on. I really hope they make the bosses scale to level like other PQs, or give them DR/pot cooldown/seduce (or like, make them challenging without giving them ridiculous skills that already exist and are annoying). I'm just glad to be able to do the damn thing again, it's been just over 2 years since I've done it.

I believe it was their attempts to make it more of a challenge that introduced the channel-crashing bug.
They closed it off "temporarily" with the intention of finding and fixing the bug real-soon-now, but were never given time to look at it.
Finally, someone there must have gotten as frustrated as the players, and said, "Let's just put it back the way it was, for now. It will be too easy, but then the entire game is too easy. When we get time to fix that bug we can release a 'revamp'."
I'm not too optimistic about them ever being given time to complete the update they had planned, especially in light of this apparent surrender.
But who knows.

I wish I could say I think VPQ might be similarly reopened unchanged, but I think making VIP weapons easily obtainable is still viewed as too "game breaking" (unlike MoNs), even with all the new sets. They won't reopen VPQ until they've scaled the monsters, or at least the boss, up.
