I'm gonna reiterate one final time for people that continually complain that they preferred the challenge. If you can't find some way to challenge yourself, then you aren't trying hard enough. There's ALWAYS something to work towards. So what if it's harder to fail? I mean, if you really want to fail you can just take a few abilities off your bar, I'm sure you find the right combination and you'll fail just fine. But I think that you'd prefer to succeed.
Just find something new for YOURSELF that you'd like to try for. See if you can still hold everything while not wearing full threat gear. Try not using cleave. See if you can do triple or quadruple single target threat. See if you can top damage meters. But by god, if you lose aggro on a SINGLE mob EVER after bitching that it's too easy, then you sirs have failed. Really, really badly. Make up your minds, face reality a bit, take a deep breath, count to 10. We're all in it to win it.
