Reactors and Stabilizers being separated doesn't really matter, if either one is destroyed, you're either at such low power that your ship becomes essentially disabled, or actually completely disabled... It's double the blocks for basically no reason, but I do like the idea of stabilizers actually needing to touch the reactor...
Could even make them look like a radiator and rename them to radiators, actually put them outside of the ship, with that distance the devs are trying so hard to keep, it would actually make logical sense then that they are farther away from the reactor, since they should actually be exposed to space to dissipate the heat generated by the reactor, could even make them less efficient for each covered side of the block, so they actually work better externally exposed, and not very good at all completely enclosed inside the ship... so then either flat panels or radiator fins, or long rods (most surface area exposed would be the rods) ... dunno if it's something they already have, but it seems like the old reactor blocks had some way of knowing if your dimension groups were touching or connected by blocks and such... Could work out and make more logical sense...
With that idea, you could remove the distance requirement since exposure to empty space would be the limiting factor that forces you to build a certain way... Might make ships look more like a real space ship would, then.
[doublepost=1507658289,1507657327][/doublepost]All in all, though, this still won't make RP ships viable, PVP will just build solid-packed ships still, you just require them to put the systems in different places now, with a couple blobs of power blocks... Still won't force empty space or make empty space any better, especially with turn speeds being based on ship's dimensions... a larger dimensions, more empty ship would be less mass, but all the superfluous blocks used for decorations in an RP ship will still make the Useful Mass to Wasted Mass ratio worse than an equal mass ship designed for PVP efficiency.
At first glance, you might think, "Aha, now there is an empty space, because of the forced stabilizer distance!" but then, I'd put shields or weapon modules in that space now on my pvp ship, versus a bunch of extra mass worth of decorations and logic thingies and doors that you might think this would open up the possibility for, either that or just completely not use the forced empty space to keep mass lower... This problem can't be solved with this method, sadly, I know there are a few different sides to the argument, but some are only arguing because they haven't actually thought about it or have some ulterior motives, like simple bias/favoritism, etc...
But just really think about it... Unless all the RP decoration blocks have zero AHP, SHP, armor, and mass, they're still going to reduce the efficiency for the mass... But then if you have blocks like that, people will use them as ablative to absorb damage with, unless you make some special property to them where weapons treat them like air for block penetration and missiles, but I dunno.
