We get lots of new four man dungeons but to me no matter what the design is, they just seem grindy, repetitive and done more for the rewards than for entertainment. Am I the only one who sees it that way?
Raids with 8+ people seem more interesting to me because there's more player interaction and each run has more variance due to different party setups, player skill, play styles and personalities.
It's the community aspect that brings the content to life and to me it's just not there in the 4 man dungeons.
