Expansions in game and raids?

[Dog Firestack]

I don't have time to elaborate, sorry if this sounds vague but:

Do you think the game should have specific areas that you can ONLY enter when you reach a certian level or a certain point in the story quest? Like you can only enter Isla Cruces when you are at Story Chapter 3: The Rise of Davy Jones. ( Made up.) I'm wondering what you think, and you have to be certain levels in game to reach certain areas.

Also, raids on certain areas that you have to defeat all enemies without dying. KO doesn't work and you have to defeat the boss enemy as well and you get a special item, such as a weapon, or an item to enhance your weapon.

Give me your ideas, I'll get back to you.
