I've been pondering on how to make shields more effective. It's the only piece of armor I use (apart from helmets) if I'm using armor at all. But there's hardly any reason for taking shields, since there are enough ways to negate the armour save they give. I mean, St4 and you've already bypassed the shield. And there's more than enough units with S4 or S4 weapons for me to leave the Shields at home. So I've been considering two options to take shields anyway. I'd like your views on them.
Option 1) let shields have a -1 to hit penalty against shooting (so enemies shooting a model with a shield get another -1 to hit). The idea behind this is basically that the shield gives you cover. Option 1A), Let shields always provide cover (being useless if you're already in cover).
Option 2) let shields give +2 armour save against shooting attacks.
