Making the game active around the clock (shards in dungeons)

One could advocate off topic opinions on another thread but is anyone convinced there’s a need for another “I’m too good for raidfinder” thread?

For example, this week’s raidfinder, T3 lower, appears one of the most difficult for the existing player base.
