As part of an industrial corp, invention is part of our bread and butter. the one major complaint from both people in my corp and outside my corp. is the fact that invention is by no means a guarantee, meaning that like manufacturing, if you got the materials to go in, you can turn it into something.
"Garbage in, Garbage out" like thinking. meaning that once you got the requirements you can get your product.
with invention you can lose millions of materials for invention only to be told you didn't get it. my answer is if it fails you should get your stuff back. so you can try again. I mean who wants to be robbed.
I think Concord should react faster period. but as far as having a higher security level, I think the player should have access to some Police gear. or even work as a police with its own set of missions and enemies.
as far as the security level of a system should illicit a bigger penalty of security status. basically look at it this way. If you have the audacity to go into say Amarr prime and start shooting up the place, then they are gonna drop you rating more, then you would if your were in a 0.5 space. since you have basically gotten in their face. think about it this way, who do you remember more, some random person walking around your neighborhood, or the guy that knocks on YOUR door.
If you attack a well known pilot to say the Amarr police force, there high security status makes them well known, as it stands right now having a high status grants you certain abilities, like using jump clones for example. and so as such should come with a certain penalty for killing a well known pilot.
As far as your question as to industrial capacity, I and my corp build alot of things ranging from munitions to ships, modules, you name it. and as with that, I mine all the time, Ice, Minerals everything. its definitely a hefty habit. the industry is pretty good, off hand i can't think of anything to change.
But I would like to make manufactured items linked to the maker when u examine/info tab, invent BPCs that when used identify the creator of the BPC, also maybe a small performance variable of manufactured goods that varies based on the manufacturer's skills.
I'm not sure how viable this idea would be, but it would be an interesting idea.
