I thought that this fuel would be for large portals, but the lost fuel is the worst on large portals.
Take a portal that needs to move you from Alycon to Maurakrib. Because of the blink distance, it needs to be large and the only way to get to that planet.

4days and 16 hours = 112 hours
If you use the new fuel that will mean you will get 336 hours or 14 days at the cost of 40 hours. That is 12% of your fuel time you loose in Oort Shards.
If you compare that with a small portal:
1x2 portal is 5 weeks 2 days when fully fueled or 37 days or 888 hours
Using the new fuel you get 2,664 hours or 111 days or 15 weeks and 6 days. That means the lost of 40 hours vs that 2,664 hour timer is only 1%.
This pans out over time. Fueling a 1x2 portal with this fuel over a year means you only loose ~120 hours of fuel, which is just a few shards.
If you fuel the above portal only with amalgam for one year, you loose ~1,040 hours of fuel. That means you would need to lose just over 3 stacks of Oort Shards just to use the Amalgam on a large portal for one year.
The problem ramps up quickly with large portals, and I thought this Amalgam was supposed to be the solution for large portals? It punishes large portals far more than small ones, so that can’t be the solution.
Here are dev posts suggesting that increasing Oort fuel would help:
I thought this would be the solution, but it doesn’t fill the role…
I would love insight on this. Is the math off? Is it intentional? Is there a solution for larger portals that won’t cost a fortune to have need a refill at a reasonable time?
Big portals are good for the server:
I want to point out I am not adding these dev notes to suggest that communicating an idea has somehow locked them into delivering a specific product. I totally understand that along the way development changes and I appreciate the Dev’s willingness to share information with us and their thoughts. The math just seems off here and I want to share why I THINK it might be a problem compared to some expectations of what I thought the fuel was supposed to do. If a Dev came in here and was like “Yea, that is what we thought, but we changed direction and it is working as intended” I would totally understand and not have anymore questions! I would open a suggestion thread looking to have what I thought this was going to do! <3
