Yeah, VICIOUS is ment to be post-endgame content (or in some cases something to keep crazy veterans busy while the devs work on the game and adress all the issues and consider all the feedback from regular folks. Or take a vacation - one time they set us up with something that wasn't ment to be beatable while they went to an expo or something. The aftermath of that episode was all major strats getting nerfed and that dungeon being made a bunch of times more difficult. Not to mention a doorstopper-worth of text in discussions, complaints about some classes being overpowered and genereal whining. Someone could do a seminar just on the backlogs
(Come to think of it I wrote a spontaneus, if a bit too technical, wiki on damage spiking at some point during all that, in the form of a textwall filled forum thread...)
So in other words, just when you think you got it all figured out, the game upps the stakes. And then you think you know what the best of the best is, someone comes up with something he's been using all along that you never touched, you fire up another profile and swear off your old safe techniques and discover a whole new game. It's... There's nothing like it, really...
