An simple math analysis of "Leadership vs. Attack" leve up dilemma

[maltz]

There is another issue about the timing of taking Leadership during a level up. Here comes a few assumptions (hopefully everybody agrees on them):

1) Nobody ever reaches Lv31 because of the insane exp requirement.
2) The amount of Leadership increase is proportional to level.

Therefore, it is better to take Leadership at level 30, 28, 26.... than at level 29, 27, 25..., because you get 60(w)/50(p)/40(m) more leadership per two levels. The difference can be high as 900/750/600 leadership at the end.

Yet we know the game is highly random. In my game I found two General's Baton. After upgrading them both I walk around with 2000 extra leadership and a bunch of happy human.
