MMOs are group based games and SE needs to remember this.

I am all for solo content, but they need to keep the game focused on groups. Group XP leveling should always far exceed what is possible for solo. Solo should be possible but never equal and never better. Quest are fine but they need to make them where doing them in groups gives better rewards. And "you can finish them quicker" is not enough for a reward.

If that is not the case you are forcing everyone to solo screwing over those who like to group, like in so many other mmos.
