I suggest that hardcore is nothing more than an easy mode. Killing someone is a lot easier. You really need no aim. You want knife kills? Well not getting spotted helps you out considerably. A sniper should suffer a huge penalty for being spotted. Being spotted in hardcore does not relay your position to the whole team like it should even with voice comms.
Situational awareness in a game should not solely depend on voice comms. Most players do not call out. One man coming two men coming this way. When they die it is the whole team coming down that side. Usually more pride than truth.
Sniper aim really matters not in Hardcore, a hit to the leg with some rifles are enough to kill you. Where is the skill in that.
I am a fan of hardcore mode in most all games. I think this style needs to be rethought. To remove all the hud and simply making kills easier is not hardcore anymore. Lets take the sniper class. You are suppose to be stealthy. So the penality for being spotted should be an a spotter icon untill your death. Having to evade and survive is what I consider hardcore. Anyone can get huge sniper kills with no replay cam with the weapon killing no matter where you hit. Hardcore I say not really.
Come on if hardcore then make it hard. Do not just remove hud and make it easier to kill. Nothing hard about that. Add more features make it so much more difficult. Then maybe we can call it hardcore. Right now it is
just easy sniper and knife kills.
