Majority of people want extra arms. I know this is [b]#Offtopic[/b], but I'd say[b] quad[/b]-arms [i]wouldn't be that bad[/i] of an extra. Lots of text, yes. Yes, I know the picture is Destiny content, but I am only saying that an extra pair of arms is a good idea. [spoiler]Also, it's very possible. Just add motion sensors and a robotic harness with +2 arms, then your wish is granted (more or less). Then again, they also have 4 eyes. You know what else has 4 eyes? Collectors. Proven: Fallen are spawn of Harbinger-Reaper. [b]Now, back to the subject...[/b] Imagine all the extra stuff you could do. Climbing would be easier, using tech will be easier, holding a [boat] ton of wires wouldn't be so messy, and fiddling with things that require more than 1 person now only requires 1, [i]because Fallen[/i] (-2 eyes). It's just an extra pair of arms (we're all pretty much born with symmetry as a natural bias, there is always 2 of everything; your action has consequence, good and bad). That extra eye would be in your hair, and you'll have some sight issues. You'd be better off with something else. Perhaps a functional, useful, tail? Maybe Sangheili-style legs? Or even an exoskeleton? I'd like a set of draconian wings with flight capability which would be pretty useful as transportation...[/spoiler]
