And what is your long term reasoning for this? Having 11 RR plus the 50% reduction on magic buildings is cheaper for Amuni chapter and probably the next than the 1 blueprint. Do you think that after the Amuni you will need more space for residences?
Yes, the next chapter will require more space for the Magic Residence. Looking at the size per chapter, the residence and workshop get two chapters at the same size, and chapter 12 and 13 were the same size for the residence, so chapter 14 will be bigger, probably going from the current max of 4x4 to either 3x6 or 6x3, maybe even 4x5 or 5x4, but that would be a bigger increase than any previous time. I guess there is also a slim chance they could get smaller, since that did happen one time when going from chapter 5 to 6.
The Magic Workshops should stay the same size, though, since chapter 13 is the first chapter at that size.
As for the RRs, I can see them making a 10-chest tournament hand out 20 when you open all the chests, in case the chapter 14 residences are 20 squares. Then you would get enough to upgrade in chapter 14 just like a BP would from the 10th chest. But that still leaves the issue that a chapter 11+ workshop being 21+ squares, so 20 RRs would not be enough to equal 1 BP for that. Then the only way to keep it fair relating to the high chapter workshops is to put even more RRs in the tournament chests. Or they may just add them into other places to earn them and say to add them all together if you need 24 RRs for your chapter 13 magic workshop.
But yeah, 20 RRs could go something like this: 0 in the first 5 chests, then chest 6 would have 1, chest 7 would have 2, chest 8 would have 3, chest 9 would have 4, and chest 10 would have 10, for a total of 20. that still makes the 10th chest worth it. Or if they want to restrict them a bit more, then 15 from all 10 chests, with chest 6-8 have 1 each, chest 9 have 2 and chest 10 have 10. Or to let the smaller fellowships have a little access, give them out in the even numbered chests, so 2, 4, 6, 8, and 10 would contain 1, 1, 1, 2, and 10 respectively. Or even 1 each in each odd-numbered chest and then 10 more in the 10th chest. Then my fellowship, which tends to complete maybe 4 chests a week when we are not pushing hard, could still get a couple a week and upgrade something in a few weeks.
