Flame me, curse me, do whatever you want, but I believe that shield extenders should increase your hitbox by minute amounts. Not too much where you can clearly not aim at someone and still hit them, but not too little where the drawback isn't big enough.

I'm here coming with 2.5 years of EVE experience, and it's basic knowledge that adding shield extenders increases your signature radius. So how does signature radius affect things?

First of all, the larger the signature radius, the easier it is to lock onto that ship. In Dust, this would make players more detectable.

And second, missiles and turrets in EVE have bigger chances of hitting ships with a higher signature radius. The only way that this can apply to Dust is to slightly increase the hitboxes of players. But again, these changes will actually be smaller than what a shield ship in EVE can experience. I've managed to increase my signature radius twofold, but increasing a person's hitbox twofold will be gamebreaking.
