I'm the opposite.
I would like to see even more differances in the regular and phased shields. I would like to see the ability "skips phased shields" added. Then you could create phased skipping weapons too, give a use for the Menson bLaster maybe. You would have to really know the enemy then!
IIRC there is a bug when shield type are mixed so that would have to be worked out to but then you could have 10 levels of each shield and additional variety. It would probably require a lot of AI adjustment though
