The current "leader" role is the "support" variant of a bunch of different themes. Leaders provided healing, saving throws, and bonuses - be they movement, attacks, temp HP, or vanilla +1 and +2 boosts to hit or damage.
If the Fighter is the Super-class, the Warlord is the Leader-role sub-class, in contrast to the Striker-role sub-class (Slayer), or the Defender-role sub-class (knight).
The knight is supposed to be a giant tin-can, heavy infantry that's the toughest nut to crack on the battle line. The Warlord is really the officer's role - inspiration, tactics, and leadership as primary sphere with the personal combat aspects (hitting enemies, getting hit by enemies) being less emphasized compared to the other types of Fighter builds.
