This is a kind of a silly question, I know... But the rulebook states they are a net, cap or a headband, right? now, why couldn't they be, say, an armband or such? I understand it reads... brainwaves... or... Something, right? Or what is the reason that it seems like it's necessary to wear them on the head?
The main reason I'm asking this is because I find a trode net/headband/cap to be... quite awful, in terms of how I imagine it to look. Though, the DNI has quite a few perks for every character class ever (my favourite is to have sunglasses with an imagelink and a DNI to let you realistically do anything you could do with your smartphone by thinking about it, from sending text messages to taking pictures and video and sharing it between your team-mates, even in the midst of a firefight. Fun stuff.), and wouldn't necessarily want a datajack due to either being a magician or just... not wanting it. it's a hole drilled in your head. ew.
I -KNOW- that this doesn't really matter to any rules or such, I'm just asking because I'm curious and need to know how to explain it flavourfully.
