Good changes (mostly). What is to stop me from making a small cross section L core with L weapons? Because I can see that being meta. IMHO core sizes need some built in invisible cross section to them that prevents the behavior I have described. NQ I am a 16+ year EVE veteran that played at the very edge of mechanics even personally forcing the developer to change there game due to my creations. Let me make something abundantly clear WE , I will abuse mechanics to the absolute degree if we think it will give us an advantage over our opponents because winning is more fun than losing. So when you make changes that effect PVP or the economy you really need to have a think on how players can and will abuse your changes. Because I promise you I and WE will. I am going to shift to L cores with small cross sections and L weapons and my ship will be more potent than an XS , S , M with the same cross section.
IMHO larger core sizes need to some extent signature blooms baked into the core to combat the scenario I have presented. I will illustrate below.
XS Core ship with 20 voxel wide front = 20 voxel wide cross section
S core ship with 20 Voxel wide front = 25 voxel wide cross section (s core gives 25% bloom)
M core ship with 20 Voxel wide front = 30 voxel wide cross section ( m core gives 50% bloom)
L core ship with 20 Voxel wide front = 40 voxel wise cross section ( L core gives 100% bloom)
So you can see from the example above baking this into the cores stops the abuse that I laid out we players will do. So the next argument will be "well why use a larger core" the answer is because they can hold more armor more container space for replacement elements and so on so you can stay in the fight longer. Also destroyed elements should be have some material that could be salvaged by players so people can have spoils of victory in pvp. I don't actually care about loot in PVP the experience is what I play for but I admit and understand that others see the loot as an integral part of the experience and reward for victory. So being able to somehow salvage some monetary value from a vanquished foes battle steed will go a long way in appeasing a good portion of your players.
Next critique is destructible elements. For PVP this is an awesome change for non-pvp not so much. My suggestion is for non-pvp aka collision is that collision cannot break an element ( make it red) only damage it ( make it yellow). ITT several players have illustrated that due to bugs , things not loading or server / client issues desynch etc leads to ship crashes or collisions. So I would highly encourage you with a rethink on non-pvp element damage or you will have a large part of your customers gnashing teeth.
In closing I just want to say that in a Sandbox MMO destruction is the seed of life. I can go on to ad nauseum of the hows and whys justifying and proving my point. However someone did a much job than me in a much better way. Let me introduce you to Jean-Baptiste Emmanuel Zorg from Zorg industries in the cult classic Fifth Element. Enjoy the clip!
