This mod changes the command point limit (population limit) in skirmish and the campaign. For good factions, the command point limit is now 600 (For the campaign it now starts at 300 and caps at 600). For evil factions, the command point limit is now 1200 (For the campaign it now starts at 600 and caps at 1200).
An example of a max pop army while playing as Mordor. I could only get about half the army to fit on screen at a time.
