Green confusion from a P99 casual. Pls help

[Furorr]

Feedback from Green players is that they're playing something new, and that makes it better. They don't have to raid fear, Kael, or ToV.

Uh

Aren't they just leveling up to fight fear golems, naggy/vox, then later trakanon, and then after that be time locked back in fear, Kael, and ToV?

Am I missing something? Is green a new game? New content? Are people just taking 50 step backwards to go 50 steps forward and end up in the same spot with more work? Am I crazy?
