Did they expect to serve players whose sessions run about 3-5 hours in length? If they did expect to reasonably serve them, then I think Shazman's criticism is valid. The tool fails to serve that segment of the market well.
I think it was intended to serve this group of players. It may not have intended to serve just that group, but I'm pretty sure it was one of them. A while ago they said something about their research showing that the average player played around 4 hours once a week. Another bit of evidence for this is that LFR modules are "supposed" to be completed in 4 hours. They ususally contain three combat encounters plus a skill challenge or two. That means that the combat encounters should take about 45 minutes to an hour to complete. If you go into an LFR session and actually expect it to be done in 4 hours with several 45 minute combats,from my personal experience, you are going to be in for a rude awakening. In reality. most of the fights will take an hour to two hours (sometimes more) and the mod will take a minimum of 6 hours and as long as 9 hours (or even a staggering 12 hours in paragon). If you always play low (all adventures have high and low level options), have extremely optimzied characters, and rush through the fights by just throwing down you dice and barking out damage and conditions (convention style) you may be able to finish it in 4 hours, but I don't think that's how most people want to play, nor is it realistic to expect them to.
