Character items

why cant the items u buy for ur guy only last for like 7 days y cant they be perminent? Can u make the items that have no effect on ur guy stay permanent? so then ppl can look more indendent. like y cant the face gaurd for swat stay? or the staff seargent bag and helmet be perminent, etc. but like the 10% bonus mask and helmet stuff doesnt have to be permanent. wat do u guys think?
