Once you've learned the mechanics of an instance it becomes boring if you do it enough, that doesn't change with either system. Even now with everything on farm mode, if you want new mechanics you go to a different fight. What I proposed won't fix the issue of something getting boring if done enough, nothing can really do that. I'm proposing a way of making content more scalable so more people can get into it and so devs can "hopefully" create more content. By having more content then there's more stuff to farm and less boredom or burnout.

I don't think my idea is perfect but I think it has more room for devs to work with it than the existing system.
