The difficulty of Normal Content in this game needs to increase.

If casual content is made hard enough to provide challenge to veterans player, it will likely become a brickwall to new players.

The casual content of the game should be challenging enough to a casual player that they have to adapt and grow as a player in order to complete it.
Having 0 difficulty MSQ/casual content in the game does not promote player growth, it just causes them to sit back and lazy ride the way through the game without the need to ever learn.

When those players reach the end game, and jump into current tier dungeons/raids, even on normal mode, they die to mechanics like AOE Circles, because throughout the MSQ, they were never punished for standing in them.
