I don't take offense, no worries. But yes, it is you and the people you play with. Also, notice NONE of the events you mentioned are Incarnate content. In Incarnate trials the caps are somewhat higher. But yes, fundamentally, the players who discuss issues on the forums have NEVER been representative of the player base as a whole. Most content, done by most players, does not have everyone constantly at the cap for everything but damage.
And also note that the REASON damage is all that matters to you is because of all the investment you and your team has already put into defenses. They didn't go away when you got to these levels of performance. They ARE these levels of performance.
