Peak gameplay to cancel missions to reroll so you get the ones with low GP cost (bonus items and get x in less than y).
As you have shown your equipment in the beginning, let me ensure you that I have the current pentameld on all crafters and gatherers (including tools) and enough materia to pentameld my new 7.3 equipment day one. Just so that this is clear.
Spamming the same 2 missions over and over again can require cancelling another missions for up to 10 times. If they want people to play the variety of missions, they should fix the GP depletion. As it stands, even with the missions you highlighted, you wont be nearly as fast as crafters in getting points.
And before somebody questions my commitment into cosmic: I had my relics 11/11 done on day 3/4.
These are my current points:

So I really did try out the content extensively before forming my critique and offering a simple fix to the situation. I am willing to finish the grind even with the situation at hand but I don't feel like it's necessary to make people spamming the same 2 missions by rerolling them over and over again.
And I do respect your opinion but you misrepresented my suggestion as "give out pentameld for free" etc.
I may have another suggestion to fix this: Lower cordial CD in cosmic. Then you still have to spend the resource but you can refill GP even if you are doing the collectable missions for example.
EDIT:
And to reply to some of the other suggestions:
The idea I really liked was the fairy idea from Eureka :> This would add some community component to cosmic by sharing the current locations.
