Bob: Cool, I want to have a real on and off the field martial leader. Here's a draft of the Warlord -- it gets all these powerful cool abilities but I think it's fine because they aren't really better than the Wizard's spells at those levels.
Arnold: Whoa, that's way overpowered. The Fighter doesn't get anything near that.
Bob: I'm not comparing it to the Fighter, I'm comparing it to the Wizard which you said was fine???
Arnold: The Fighter is fine, but no one will play a Fighter if you add this Warlord.
Bob: What do you mean? The Warlord doesn't get heavy armor nor martial ranged weapons.*
Arnold: That's not enough
Bob: It's a lot. There isn't much else you can remove from the Fighter.
Arnold: Couldn't that be a fighter subclass?
Bob: There is not enough design space and power to balance it with the Champion.
The bolded is the problem.
If a rigid element or bad element is core to the game but also narrow in mechanical space, there is no design space to add much.
The fighter, the barbarian, their subclasses, the Monk and many spells are too narrow mechanically in scope that if elements of them are simple or bad, there is not enogh mechanical room to add anything much with it.
*The 4e warrior traded heavy armor and bows/xbows for support/
