After a 1.5 hr queue I got into AK last night for the first time. Luckily I got grouped with three people who knew each other and wanted to do a speed run. I'd watched videos on both the speed run and the bosses and given the wear ratio for fighting vs quick death I was in favour.

The bosses in AK are quite punishingly tuned. They require consistently high levels of damage while moving and switching targets and it gets to be a lot to keep track of. If we'd have had to kill all the adds I don't know if there would even have been enough time to get to the last boss, much less the couple of attempts it took for me not to die to various effects (thanks in part to the aoe bug).

In short, I don't know that many new people can complete that instance within the time limit if all the trash has to be killed as well. I am happy I've done it and now have my CG weapon but it's a larger impact on new people than you think.
