Couple of combat modifier tweaks

When I made the original VIET Traits it seems I accidentally made a couple of the combat modifiers more powerful than I intended (i.e. Just giving +20% morale defense instead of 2%) so I just reduced them to be consistent with the other traits.

Oooh, look, it's my first Github edit commit thingy.
