Thanks, LC, for giving me this link.
I would like here to revise my thesis.
LA is not getting higher base rewards by BA cost after all - I never read the conclusion found in
this thread. However, he is getting increased rewards over Ranger via RoE, and against anyone who cannot fight as high PR-wise against opponents he gets increased rewards as far as base rewards go.
This means that against most opponents, he is increasing well beyond the 23% that the RoE provides. Against Ranger, it is decreased. However, once the MPR gap widens and he can beat opponents with more equivalent PR to those Ranger beats, the base rewards gap will drop and he'll increase in rewards by the full 23% against Ranger.
This will create a snowball effect - his base rewards increase as his MPR gap increases, allowing the MPR gap to increase at a more rapid pace, until the two reach equilibrium at a point where each point of EXP increases MPR by a lesser enough amount that he no longer gains ground over Ranger.
In other words, he'll reach the point at which 123% EXP is required to make the same MPR as 100% of Ranger's. How far ahead is that? I don't know, but I have a feeling it is a pretty good way ahead of him.
Additionally, this calls into question whether or not the N*B accounts for the top character using a RoE. AFAIK, it is based on the character's current MPR and a formula that Jon has devised as to the rate at which a N*B character must grow. I do not believe that it takes into account the RoE, as that presents a few still flawed possibilities:
1) That the N*B takes into account the growth of a character during the time before the present time at which N*B calculates growth necessary to achieve its goal, which would mean N*B rates increased exponentially whenever a N*B reached the #1 spot whilst retaining its bonus; or
2) That the N*B takes into account the current average rewards for the #1 character, which would mean should the character be using a normal tattoo and happen to test a RoE at the time a N*B is created, the N*B rate would be at an increased rate to adjust for the #1 character's currently altered average rewards, allowing for a positively flawed N*B bonus. This would also correspond with the problem found in (1).
I cannot help but conclude that the mechanics of the game are likely broken in respect to the presence of the RoE, and I feel like this is certainly a bug, not a feature.
