Will it ever end lol

I’ve been playing these warzone games non stop to build points and then open a pack (mostly silvers). Still the fabled DMR eludes my grasp. Ever since I reciever this cool upgraded version it’s been itching me to find it but everytime armor or a visor. I can understand the arnor and helmets but why would you put visors and emblems in these packs. Emblems should be earned and why can’t we just change the color of our visor. This part has nothing to do with the previous but damn you would think that a self destruct button would be in the slower moving vehicles (i.e tank and wraith).
