Actually I was suggesting more so that they adhere to a tried and true system that has already been outlined rather than all the experimenting going on. This would allow for development in other areas in an 'environment' that had a strong structure, not forcing them to reinvent the wheel every year when it comes to events or game features.

I 100% agree with this. According to what we've been told the server 'can't handle' this sort of thing.

If you have a chance check out 'path of exile' - another free to play game (actually free to play, only cosmetics are purchased, with no in-game benefit other than looks). There's a labyrinth area that randomly generates every day. You can re-enter it, explore with your friends, or whatever... and in the next 'day' it completely reinvents itself again.

This allows the drain on server resources to be kept to a minimum, grants the ability to make timed runs a thing (unified areas, but in a randomized way that remains fresh even after a few months of play), and could potentially be a framework for multiple dungeon areas with different themes (volcano, underwater, desert, forest, whatever) being applied by simply changing the tilesets.
