What does this mean for me? You will always be able to play your favorite games on Kongregate. However, certain site features may suddenly stop working and leave you with a severely degraded experience.
What should I do? We strongly urge all our users to upgrade to modern browsers for a better experience and improved security.

Since I can’t find any place to confirm the gut feeling I’m having, I’ll try asking here. Do the upgrade levels have any effect at all on the production rate at all, or are the upgrades merely there to enhance the timer and max capacity of the mills?
I’ve upgraded just about all my mills to L9 and I’m not noticing anything in the way of increased rates in the past few grades. Honestly, I feel I’ve wasted my resources for all I took past L7 by now. ~~\_~~
Just do the calculations yourself – Divide the number of max wood able to be stored by the number of minutes it takes to fill up. Do the same for a L8 mill and see if there’s a difference in wood per minute.

I had aimed at 24 hour buffers as I do with all games with timers, since I prefer to only log in around the evenings and lose no charge time this way. I mostly went above L8 because I didn’t have storage space left at that time and plenty of resources (lacking the artifacts to progress), mostly an endresult of an involuntary monthlong hiatus of actively playing games and burning through most of my rare material supplies early on.
But if you’re not there yet, I feel there’s little need pushing past L8 while L7 should be sufficient if you have the luxury of logging in on a frequent basis.
For active players:
you should be able to farm wood extremely easily, so all that matters is metal. In that case, a rank 10 mine pays for itself in 78 days, which seems prettty worth it to me considering how difficult it is to get refined t6 for every hero (in multiple classes even).
For idle players:
you’re probably short on wood in all likelihood, but since you only play for a few minutes a day, u’re probably aiming long term anyway? so even though the mines/camps may take a while to pay off, u’ll probably take even longer to finish the game, so its worth it to max everything.
