6:10 - 6:38 of the video. Long range Rifle vs Rifle duel. It would've been better and quicker if one of them had an SMG to mow the other guy down. With zoom + norecoil + suppression effects + strafing left and right, a few bullets are bound to hit the target, the rifleman would have no chance. Looks like rifles will only be useful for taking potshots at unaware people. Poorman's sniper, which should be rectified by no class restriction modifiers.
Not to mention that the guy featured in the video uses SMG's almost exclusively (doesn't he have a rifle killstreak to show off?), and how every other video posted features SMG spam hints how unviable rifling is in RO2.
Looks like SMG's and snipers will be the most sought after classes. Bring on the no class restrictions quick!!!
