Tired of people manipulating or lowballing the prices.
I suggest to take an average Prime bosses killed for each top tier list rewards and devide it by 4. At the end of this calculations you can see how many letters were spent to open Prime altar And thats the prizes for it.
Week 1 letters were 1.2m-800k each so yee..

You can also add the grind hours on top of it, but it doesn't change the prize by it in my opinion.
Lmk what do you think people
