Sure, but you just mentioned it right there, the high risk high reward.
You’re obviously gonna use a Lancer at mid-range for either an open target or providing cover fire. Your chances of a kill are very slim because of just how the lancer is. Gnasher won’t cut it.
Skill would be managing your weapons for the situation, not “lol lancer for puccies,”
Skill would be managing your rate of fire, distance, maneuvering, switching between blind and open fire, and most importantly leading your shots.
You’re arguing over what weapons are the only ones that require skill, which isn’t true when there’s plenty of depth that goes into ranged weapons like the Lancer, Hammerburst, Boltok, etc.
