As soon as I get all my headshots in core FFA I switch over to hardcore CTF for my kills / streaks. Really easy to flank the enemies guarding the flag and get the 2x kills and bloodthirsty. I find it marginally easier to do hardcore without perks / attachments than core. Plus, less bullets for a kill makes the multiple kill streaks much easier to come by.
Also! Select fire for headshots. Makes it SO much easier imo, especially after getting gold on the Chicom. Extended clip, because the Skorpion shits through the regular clip WAY too fast. Laser because the accuracy from hip fire sucks balls without it
