It always vaguely bothered me that the Borg drones were individually too retarded to disrupt their routine to deal with physical assaults, or, for that matter, boarders.
And being vulnerable to bullets when a phaser blast gets stopped cold makes no sense at all. That's like a tank shrugging off RPG rounds, but getting knocked out by massed musket fire.
No it isn't. Phasers and bullets are apples and oranges. RPG rounds and musket fire are apples and, well, really BIG apples.
I agree about boarders, though. You'd have to think that at some point they'd have assimilated that having strange people roaming your ship is a security risk.
Phasers are so inconsistently portrayed it's hard to know for sure what they are. Maybe some kind of plantain.
