Changes to POBs

but 7/8 days supply with a stock-up in case of siege taking over 16 hours, even with 32 players doing 30 mins each.(unfortunately doesn't split like this even if the whole server activity was to chip in time to a single base)

All that to be popped by 12 dreadnaughts in less than 7 hours? That totally ignores the millions of units and input time required to get a base to that core level to begin with.
[and also snip]

Twelve Dreadnoughts sieging for 7 hours adds up to 84 man-hours. The stock up period adds up, by your own math, to 16 hours. That means the attackers are investing 5.25 times more hours into this whole thing than the defenders, by your own example.

That to me seems like it's still tilted in favor of the attackers.

I will say, however, that there are plans to a do a far more in-depth rework of siege mechanics, and one of the core mechanics we will be working with - in all likelihood - is "Damage caps per siege" - meaning the twelve dreadnoughts in your example would get to shoot a base for, perhaps, thirty minutes before rendering it invincible for an amount of time. It's just that we need to make sure such a rework gets all the numbers right and accounts for all sorts of potential issues.
