The issue is you need to give a people a reason to WANT to fight mobs outside of dungeons, otherwise they're just a massive waste of time when people just want to get from A to B for a daily quest. Mobs were a bit dangerous when 3.0 hit because we weren't geared up. After finishing the main story and gearing up on esotreics, we're right back where we started in 2.0 where the max level mobs pose no threat to us, but still aggro anyway because we're in level range and the RNG Heavy spam when we're just trying to get away.
