How can you compare TOP to NPO? This is war, its not about fairness, its about winning and losing, TOP could have 100 percent of their people in PM, and it still wouldn't matter because TOP is still winning.
You want to compare, you should compare them to another losing alliance that has a bunch of their top tier in PM. Say ODN, you could bring up a case that they should also get the PM term since a few of them hasn't seen a ton of war either (granted their numbers aren't as bad as NPO, but having 3 nations over 100k and under 1 million casualties is also pathetic)
