Read those older threads, they'll show you the math that proves that bypassing mitigation is a huge advantage. In fact no other weapon type comes close to the damage phase missiles can do when fully upgraded.

You can roughly calculate it as doing [(% damage increase) = (% shield bypass)] vs frigates and more to larger targets like star bases and cap ships.

I don't understand why people think the shield bypass works a lot better vs advent then other races it will a little because of mitigation techs and culture bonus but just because they have a higher shield to hull ratio doesn't mean you need to do less damage unless the unit still has shields when its destroyed (very possible but rare)

And Progenitor motherships can keep Advent shields high enough that they do in fact run out of hull points while shields remain.

Armor plays no bigger role with phase missiles then they do with any other weapon type.

This is the main possible but rare expectation I mentioned but by the time you have phase missiles teched enough to have a significant shield bypass your fleet should be large enough to focus fire on any caps in range, letting your enemy getting maybe 1 or 2 shield restore off but sacrificing the progenitor to do it.

They are more effective versus Advent capital ships because Advent capital ships are not as sturdy out the gate as Tech. Further, Tech has early access to hull/armor tech while advent has early access to shield/hull. The early armor tech does more to absorb phase missiles than the shield upgrades do. Advent's ability to get to get armor upgrades is really hindered by it's tier requirement.

What I don't understand is why people think the Advent higher shield to hull ratio is that great. The ratio is higher because the hull is so LOW. 

Look at the Psi battleship compared to the tech battleship. Is the 800 loss in hull for a measily 500 gain in shield that great of an improvement. Further the shield takes 100% of all damage from all types while the hull gets a modifier due to damage type. If you wanted a bit better balance the shield would need to be up closer to 2500-3000 starting out. They'd have some better late game survivability/scaling if their shields were up'd too out the gate.

Psi Battleship: 2200/1750
Tech Battleship: 3000/1250

Psi Colony: 2350/1450
Tech Colony: 3150/1250

As it stands currently, the shield advantage advent has over other races is NOT their shield/hull ratio. Their shield advantage is their research and shield based abilities.

Ima preety sure both shields and hull recieve the same damage modifiers.  a unit with medium armor, which has 1 hp, and 1000 shields, should die just as fast as a unit with medium armor, 0 armor, and 1000 hull and 1 shield  to a group of lrms.  (excluding passive regen)

Considering some of the others (like harpo99999 and DrJBHL ) we don't have a chance. DrJBHL has 1500+ karma points.

That was it. I set it to zero in the entity file, but it still defaulted to 15%. Thanks.

Mess with the player entity files here

to get rid of shield mitigation.
