My thoughts on the totals. My biggest concern is stifling creativity. The proposed limit of 42 max cores for a solo player is not nearly enough for them to have some ships, 2 bases and mine and create an incentive to continue to be creative. A lot of us made changes when this was brought up a few months ago and consolidated to a single personal org that maxes at 275. We've lived within that limit pretty nicely as well. I've bumped my max only once and I made the necessary changes to bring my total count down and didn't really have to sacrifice anything other than random stuff that was half built or no longer used while still being able to maintain my creativity and revenue from ship/static sales and now commissioned builds. Get rid of the nested unlimited core orgs, of course. If 275 is too much, knock it down a bit, 5%, 10%, or around there but any more than that and we're looking at no incentive to continue to play if we can't be creative and also proudly use and show creations that we've made or were made by others. We can't "win" if we can only build 17 personal items or a total of 42 if we hoard our org slots.
Increase the personal to 50ish, AND Increase the proposed org slots from 25 to 200 or so. That will accommodate solo players with a little hit and orgs with a little hit.
