In some ways, the Devs are forced to design dungeons like the current ones because that is what players have come to expect. Besides the lore and UI, many current MMOs are incredibly similar due to that fact. While I agree with the OP To a certain extent, I dont think those changes go far enough in my opinion.

This game is still in a very early stage of development and discussions like this one can help it evolve over time into something unique and different, given the right guidance from Devs. It could stay as it is and be a success, or it could become the next blockbuster that others copy.
