Just Gracie Jui Jitsu?

I did MMA for 5 months (Kickboxing,Boxing,etc.) and I did some BJJ. Now,I fell inlove with it because it is to amazing,and complex. I know Its only good for 1 on 1 but I want to know,should I drop everything and do Full time BJJ? its allot cheaper to. I am really considering it.
