We do not know how many RRs will be offered outside of the tournament. We do not know the difficulty the tournament will have after the fix is done. There are a lot of unknowns.
What is known is that the current spread of RR among the tournament chests makes the effort of getting 10 chests much less appealing and that every RR offered outside of tournaments(if any) would only increase this effect.
9 chests get you 72% of the RR for 80% of the points
8 chests get you 55% of the RR for 63% of the points
7 chests get you 45% of the RR for 48% of the points
6 chests get you 36% of the RR for 35% of the points
5 chests get you 27% of the RR for 24% of the points
4 chests get you 18% of the RR for 16% of the points<--- This is now the best RR per point sweet spot.
3 chests get you 9% of the RR for 9%% of the points<---This is about 200x cheaper per RR than getting 10 chests
Once you consider that the higher points cost far more than the lower points e.g. the 20th province costs 20x the first province, then you can see that the return on effort is massively skewed towards those who try less.
