I feel the new classes should start at level 1.

We were told that restricting access to the expansion to new people was a mistake, and that they wouldn't do that again with this expansion. In Heavensward, you already had to have a level 50 class in order to pick up one of the new jobs. If people can get to (or even start in) Mor Dhona, then the new classes can't be started at level 30.

Did everybody forget about Ninja? They started at level 1 as rogues.
