Level 50 Zones need to reward experience...

[Nektulos-Tuor]

People also derpowerollevel in Northern Thanalan, but that's what bots and lazy kids do. It requires no skill to just faceroll over content, especially content that you're overgeared for, so the botters just kill easy stuff to level their bots.

Hence why using the MSQ as a gating mechanism keeps bots out of the highest level parts of the games. You can't make a bot have any level of skill to get through the solo parts.

So, I still fail to see your point. Explain why the level 50 zones exist if they don't give experience to you unless you have the roulette unlocked? It basicly means there is no point for new players to unlock the dungeons.
