Depends, I haven't checked your work, but are you just doing one single brand? Because, if so, I'd expect that your roster would have to be quite big if you're gonna have 4 titles. If you have a small roster (25-30 people) I say scrap one of the titles. No need for a lower card title, imo.
yes my roster is big,im having a main title, midcard title, tag and a women's title, you see i want vareity on my show so i wanted all aspects of wrestling and say if i scrap the midcard title, there will be so many wreslters competing for nothing i you know what i mean.
