Let's correct this now: however as it was in the past, as of 6th edition both Banshees and Scorpions have Fleet, and neither has an advantage over the other. Scorpions are not slowed by their heavier armor. Also Banshees are utterly annihilated by Overwatch and Flamers in 6th ed. Let's not be too starry-eyed: charging into combat across a clear field of fire is as utterly suicidal as it's ever been. Only mob-oriented armies such as the Orks truly profit by those "tactics." Approaching through advantageous terrain is far more viable, and Striking Scorpions are trained to Move Through Cover as much as Infiltrate and Stealth. A noise is more novel than *pewpew* head-lasers? It is your opinion and the conventions of conversation accord it a base amount of respect, but I reiterate my disbelief. It's been done. Whatever useful material effect as may manifest, that base is more assuredly covered. Every faction in this setting except Tau, Necrons, and Tyranids carry a chainsword of some kind as a CC weapon. And power swords are almost as common. I ultimately do trust that the devs can depict whatever weapons are chosen with sufficient artistry.
