This is the what a lot of forum posters who complain about difficulty (hard or easy) lose sight of. They are too subjective and personal when it comes to what is 'easy' or 'hard' or 'fast' or 'slow.'
Also what folks seem to forget is that while Turbine does not report the numbers to us, they have statistics showing them who runs what, how long it takes, etc. Just because a large percentage of frequent forum posters can run wiz king elite in under 10 minutes with zero deaths does not mean that is the 'average' time for the player base to run it, nor should everything be scaled to satiate this group.
The reverse is also true. Joey Newnew coming to the forums to post that Water Works is 'impossible' on elite should also not be catered to.
