Do not force level caps on content - You segregate the player base

That's their fault, then.

I did Toto-rak at level 30, and Shposhae at level 20. If I can restrict myself what's stopping anyone else from doing the same?

The point is to make long lasting content, however if most people are over leveled then do all the content, it can be beaten very quickly, I'm not talking about Difficulty of the Mission/Quest, I'm talking about ways to make content "last" and not "Rushed". Most people if they see an easier route to beat the content available, even if they don't want too. temptation will be there to actually do it.
