No unrealistic perks (such as Marathon, Double Tap, or Commando) and make perks like Stopping Power, Juggernaut, & Extreme Conditioning add-ons to the player's weapon(s) or armor. Also, perks will have some downsides (like added weight). Also, different armor should be choosable (like helmets, boots, knives, and body armor). Original killstreaks would be boosted by 1 kill (except with the Hardline perk, which actually was a good perk). Weight would be attributed to certain weapons, but can be carried with some ease with reduced equipment (which leads to less weight). Only certain weapons would be used with the Overkill perk (yes, pistols only).
