Falconer: Eh, yeah, the explosions probably would mess up anyone inside, even with Plexiglass. (Just remembered the name now.) It might be considered 'overkill' to have three or five layers of plexiglass overlapping, at least one cm apart each, with the outside two or four lined with Smart Armour. Yeah, you lose part of a layer, but it should be plausible, though costly, to stop even a minigun for a Round or two. For a Mage, able to cast LoS, to have that kind of protection, even one-shot, would be worth it on high-risk missions. Have a Trode Net or something on the final layer broadcasting the Dalek skin, so the enemy, if they're using AR, can't even see the damage they're doing.
Now I want to play a Dalek Rigger. Definitely sounds amusing, and I could have my main Drones share the same motif, so nobody would even know which one to shoot.
Come to think of it, hiding inside your own remote-controlled weapon has already been done by Naruto.
