how do you think an all seer session would go? I can imagine it being split between: Do almost nothing but suggest things/give advice, and do everything, mainly relating to the respective aspects, because they know how to and no one else is doing The Thing, whatever it may be, with the best ending, in my mind, being a super knowledgeable circle of seers that win and claim their prize of moving into the new universe pretty easily
I bet it would be them getting spoiled about the entire Session and struggling to determine what is a Stable Time Loop and what is a Doomed Timeline, arguing about outcomes that conflict with each other and constantly warning each other about every action they take. They would get shit done though.
