YES agreed, there are a lot of hardcore players that aren't playing as a clan or team.
Don't care too much about the clan stuff, but YES PUT ALL OR MORE GAME MODES IN HARDCORE!!! Why do the hardcore players get so little love in these games?! Also, it would be great for when you kill people in hardcore that you get the +100 or whatever put up on your screen. Right now you have to take your eyes off the sights to look at the kill count to see if you got the kill. Seeing just the hit markers is no guarantee that you got the kill (which is really frustrating).
