Well, I think that Merlin should pass around who it's main villain is. Only because it comes to a point where there story gets excessively pushed over the line (like how Gaius' story is). If Morgana comes back in every season within an opening two parter, that consists of her failing by the end of it, we'd get totally sick of it! And if she is there all the time Merlin would start to look like Mario and Bowser, or more like the Koyote and Roadrunner, where they just: fail, fail, fail, fail, fail, fail, fail, fail, fail, fail, fail, fail over and over again. And I guarantee you that this will come to a point where it gets unrealistic.

Like this meme is a great example:
