"Armor - Regular armor is really not viable in the longterm: It's damage/kT ratio is lower than shields and it requires repairing after combat. I have always thought it should have a better damage/kT ratio than shields *because* it needs to be repaired. Hopefully armor can be improved so that there is a real choice between shields and armor in the mid to late game."
Easy enough to do..
By that same token, I cannot think of any non-racial armor-skipping guns except for the null-space cannon and of course the special weapons (engine/weapon/computer killing). The problem with nullspace is that it skips shields too. It would be nice to have some more armor-skipping weapon choices. They should be at least as expensive as PPB's. And consideration must be made for crystalline/organic races. If everyone gets armor-skipping weapons real easy then these races would suffer."
Yeah, they would. I like having more armor (and shield!) skipping weapons though.
Geo: this is like what I was doing for techmod, only explained better!

Hopefully you can pull it off better. I got bogged down in the missiles section of the tech tree (5 missile levels, 7 warhead types, ~50 entires PER WARHEAD TYPE.. ug)
