Vaal Temple (Co-Op) Progression

We are 2 freinds playing together in the new league, and we dont both get progression to the 6/6 vaals platform, only 1 get it and then the other person gets it next time but its not 100% certain, its seems that the party leader gets more often then the other guy who isnt party leader, and we only get half of the progression towards the temple then we would if we did it solo, so we cant both use the crafting benches in the temple, so we actually lose 50% of the progression compared to duing it solo.

i know we both have 2 diffrent temples and their own progression, but a solve could be if u could still have either the half progession system, and did so we both could use crafting benches (in Coop), then it would be the same as duing it solo, cus right now we lose 50% progression towards the temple.
