I always play hardcore so, usually one to two shots with anything takes someone down.
I like the new weapons due to its something different from 4. Even though I would prefer modern, its nice to change it up a little. It does seem right now that sub machine guns do a ton of damage. Have to remember though this is BETA, when I was in beta4 the M16 would take out 3 people across the map.
I dunno what your getting at with “changing the sniping system.” But i’ll tell you my take on it, same as cod4 but with scopes you can actually use, thank god. For instance, when you equip a scope on a rifle it *increase range, AND accuracy! Instead of the ole’ cod4 with increase range and horrible accuracy with the AGOG.
The ranking systems a little different now also, you can break down your ranks in terms on game play choice. Meaning if you play hardcore like me all the time then your regular deathmatch/search/war etc rank will be low.
