If this does not change then this
is a lie.
Even so, it would really only screw beams and cannons as alpha weapons, but missile alpha would only be stronger in comparison, as any volley strong enough to break shields could easily overheat a ship or get near to that. A block damage weapons system would have to be able to effectively hit where the shields are downed, which hurts alpha, but at least shields are downed instantly, and could probably hit multiple areas since each region has weaker shields, in the case of dps weapons, those shields take longer to break in comparison to alpha and if the shield area that was opened up isn't large enough for your block damage to get through, then you need to open up more holes in the shields, which takes longer than it would for alpha and only hurts dps weapons more. I get what they are going for, I like the idea of having some areas have better shielding than others, but this is the worst way to do it, it screws most weapons systems, but buffs any missile boats.
The middle part of that paragraph isnt the most coherent thing that ive ever written, but dps will be as screwed as everything else.
