My point is that what you’re saying is exactly what won’t happen. Let me show you some basic math behind this concept, since you seem to be so fond of percentages.
Let’s say we have two corps, A and B.
Corp A has 100 members, Corp B has 50 members.
Both corps are tied on the rankings with a score of 1000 each.
Both corps gain score at the exact same rate, a rate of 100 per hour.
Now, before the loss update, they were always tied, no matter how many more people one corp had over the other.
Now, let’s factor in the loss update, losing 1% score per hour.
Because they have 1% less score per hour, we can effectively say that their score gain rate is decreased by 1%, while their max score remains the same.
Corp A had 100 score per hour before, and now have 99 score per hour.
Corp B had 100 score per hour before, and now have 99 score per hour.
Well, would you look at that? They are still gaining score at the exact same rate, leading to the exact same deadlock in score. This is true for any two corps of dissimilar sizes: As long as their score gain per hour remains the same (which it, by definition, does, due to them being so close on the scoreboard), then they will remain at the same rank. Corps will only rise or fall if they start to do worse in their games, or become inactive.
Therefore, having a flat percentage rate apply to everyone is the absolute most fair you can be with a mechanic such as this.
