If this power proposal is anything like I think it is, it would actually make titanic dreadnoughts a lot
more powerful than before, because getting rid of powercap blocks means you can stuff the empty space between reactors and stabilizers with that many more shieldcaps.
This is an old, unfinished dreadnought I was working on, compared side-by-side with a picture of the PoA from Halo:
It was a good 13-million-plus blocks. Nowhere near practical for actual combat. It had 1,230,000,000 power cap and like 60 million regen, 100+ million shield cap, a few million shield regen, etc.
Before the nerf, the 900,000-block punch-through cannon array would punch through many kilometers of solid armor. The nacelles were completely full of blocks. Now, if it had reactors in the middle and stabilizers at the ends, and everything in-between filled up with shielding, it would probably be near-invulnerable. Getting rid of powercap blocks and giving each weapon and device its own dedicated buffer gets rid of the need for millions of blocks in this design, allowing for more to be allocated to defense.
