The campaign puts a ceiling on the upgrade level of your heroes in each map, so that you can't have a lvl 30 leader before you even get to the second map.
Is there a way to do this in a custom scenario? That is, set a max upgrade level for heroes. That would really cut down on uber-heroes if you can't go above, say level 10.
