As pointed out by Rooster, medical itself is already difficult for people to get into. I've always wanted to get into medical throughout my years of SS13 experience, but it's never been something I've been able to simply because the complexity, no matter what server. Is it difficult for someone who's been in medical for a few months? Probably not. But for someone new to medical, it's a daunting experience. Knowing that it has become more difficult, it's going to be seen as too difficult for some people.
I guess something important I'm also wondering is, who would the change benefit? It seems that this change would only be benefiting medical players who are tired of the routine, while hurting the rest. I feel like it wouldn't be adding any roleplay advantages (I could be wrong), and is just there because it seems too easy for you.
Personally I think if you're finding a department too easy, that may be a good excuse to try out other departments and learn new mechanics. I don't mean that as in "you should play something else instead of changing everything!", but instead I feel that certain departments lose their glitter after playing them too long and a perspective shift can be helpful.
