The less than 6500 passive is to add an XC1 Transport Probe. As to large XXXX over Rings it is a matter of choice.

Math use to show that rings were always better. Has that changed with more ap/size buildings?

My best rift has rings but I would get more production from it if it had large moons.

This is because the production caps, and buffs beyond that point add nothing. I have wasted many, many Elios buffs, Vara buffs, Lepus buffs and Q-pedd docking buffs over the past 2 years.

However, if I had the extra space so that I could add planet structures then the production would increase.

Large Moons better than Rings IMO.

this is nonsense. you said yourself that 'production caps'. so how will adding more production make it cap less ?? if you had moons .. you just apply fewer buffs to get to cap.

once you know a production buff will be 'wasted' .. you use it on the next best planet. continuing to use it when you know there is a cap is pretty dumb.

someone having t'issues' with a 63x arti dyson isn't likely to garner much sympathy.

i'm not being 'hostile'. i'm being BLUNT. there's a difference. i have no expertise with 63x arti rifts. but i have some facility with basic math. you are free to offer bad advice, but when you do, you shouldn't expect to go unchallenged.

if there is a planet production cap (about which you seem to be contradicting yourself continually), it really doesn't matter what combo of planet structures and buffs will get you there. you're going to hit the cap and you're better off placing that new planet structure / planet buff on your next best planet.

if you can replace a current building with a 'better' production building and the production increases, then you haven't reached the planet production cap. rings will always be better than moons in that case since any extra space will only give worse production structures than what you already have.

for anyone else without a 63x arti rift, trying to squeeze out higher base production from structures to save on applying one of the planet production buffs seems to be the height of silliness. put the structure on a new planet that isn't going to hit cap instead and keep the production % buffs on your best producers.

How can your Rift Cap at 98k artifact ??
Mine is capping at 65k

Without seeing your planet build, the buffs, and the order you are placing them, I cannot speculate as to why your planet caps lower than mine.

The order in which the planet buffs are placed affects how high I can buff mine. I have spent 2 years experimenting, wasting buffs (because I am dumb), changing the order in which I apply the buffs to get the absolute best result.

My planet produces 98k without applying Q-Pedd Docking Station, Gift of the Makers, amongst other buffs that either take no effect or apply the incorrect increase when used.

I am still working on exactly what the minimum amount of buffs are to reach the cap so as not to waste any, so I can apply these elsewhere.

My advice to you regarding placing your buffs based on my experience would be to add Klorvis as the final buff, Trelth as the second last buff, as these both seem to always take effect. And to experiment with the order of the other buffs. Hopefully you can get your cap to increase by trying this.

Today I finally received an apology and recognition from support that there is a cap and that they are still unable to resolve it.
