So Snipers are only to be feared in the sense of that they will weaken you in a fire fight...What if you wanted to snipe and get kills... if one head shot won't get a kill then will a person sniping be no better then damage support? I think Brink will be an amazing game and I bet the developers will think of something.
Last little note. Maybe if a sniper gets a head shot they should get a % of chance for a 1hit Kill or not.... like, someone needs support from a distance and the sniper that replies to the call, gets a head shot... maybe because of his rifle customization gives him a better % of getting a kill with headshots.. yet slows down reload speed or fire rate or something.... Please let me know what you guys think.
Keep in mind that the Short Rifles are a light weapon, to be used either as a main weapon for the weakest bodytype or a sidearm for the medium bodytype. Giving the light bodytype a weapon that has the potential to kill faster than any other weapon would really unbalance things. At the same time, being able to use a marksman's weapon with the acrobatic bodytype makes the most sense. This way, there is a compromise.
Also keep in mind that there is a lot more time required to kill someone than in most modern games, and if you are starting a firefight with someone as a sniper knocks you down to half health, you're suddenly in a very bad position.
Lastly, SD have stated that they have no interest in including OHK anything (except possibly in rare occasions). That is because its just not fun to die before you have a chance to shoot back or even struggle. Dieing before you have a chance to realize you're in trouble, and having to wait for a revive or respawn is really anti-climactic and boring.
