I had to hunt down each skull on my own, then invite my brother-in-law and sister just to show them where it was, just so that they could get the same.
I remember when the final Mythic Map Pack was released, I had to do a helluva lot of work just to get my bil and sis up-to-date with me; when we actually unlocked Recon, I got to deal with 13-year-olds asking "Hey, can I kill you so I can get Recon?"
Then of course, the teabagging was relentless. Sorry, but I like the Mark V helmet with Katana chest, Recon pauldrons. However, MCC doesn't let you have that kind of deal.
I like displaying what I've earned; yet kids these days would rather jump straight to Katana 'cause that's what's availible.
