I need access to edit and/or delete system defined fields. I need to customize the CRM in a way that makes sense for my business model. It won't even allow me to rename these fields. So I have fields out there that I will never use, yet they are taking up space on my data entry screen. 

My assumption is that if support has access, then I can be granted access. I'm at a standstill, yet again, with my conversion.
