Hardcore mode for veterans and those who prefer simulation

I'd be fine with a Hardcore mode that was more akin to what we've come to know; short TTK, limited HUD, etc. Obviously not 1 hit kills or else SMG's would be even more dominant and impossible to deal with.

What I will say, however, is they'd probably also have to restrict weapons to classes like they do in the other game mode, and limit how many snipers you could have on a team, otherwise a lot of maps would have 20 snipers and the inability to do anything.
