“Blame ArenaNet for the right things and yourself for all the rest.”
I decided to stop reading after that cheerleading remark.
It’s great that you feel the ArenaNet is ominpotent and can make no mistakes, even though they’ve acknowledged that some dungeons might be too difficult. Be that as it may, the problem isn’t just the difficulty or non-difficulty of particular dungeons – it’s the reward vs. time/frustration factor.
