flamer and heavy flamer by far contend as the best close ranged weapon for dispatching players rapidly
navigating without attracting attention to yourself factors down to how aware you are of other all the other players and how much of a relevant threat they pose to you (weapon wise atleast)
you probably wouldnt fret too much over a guy with a sword over a guy with a mas rl
meaning you might hover around the sword guy knowing that even if he saw you, he wouldnt be able to inflict any harm upon you as long as you maintain distance from his weapon's reach
whereas the mas guy-100% of the time you want to avoid detection
not only since the mas rocket has ridics dmg, but also due to its massive radius dmg which does not care if youre on the opposite side of a wall
if the mas rocket has close proximity, more than likely you will suffer high dmg or death
since the rocket arcs, its better to maintain distance and not be seen in the 1st place
accomplishable by making use of cover or vehicles in order to travel from point a to point b
