I'm guessing it's because wraps take up a lot of server space. I only have about 7 wraps saved and it's already taking up 30 MB, might not seem like a lot but imagine if every player uploaded 50 wraps to EA's servers. My wraps aren't even that complex.
As to why they won't allow us to save more than 50 wraps locally, well wraps also get uploaded when you join an Online speedlist with them.
Just to be clear I'm not defending them. Seeing as how bad the netcode for this game is the least they could do is put up more server space for wraps.
