In 4e, most of the Dailies for Warlord are simply the mechanism for dealing more multiples of weapon damage. In other words, low-level Dailies are moreorless indistinguishable from high-level Encounters.This is the advantage of using a common general structure.
Dailies: some maneuvers are only rarely likely to occur in this case rare means once a day which one might think of as about as often as a critical hit. Now you get it reliably as a player tactical choice because fate likes heroes and OR perhaps the character can put special effort into it and in the process straining the muscle that lets them do that superhuman leap and which recovers after a long rest (or whatever). The details vary by ability somewhat like the Tricks and so on mentioned earlier for encounter abilities.
Not only casters can do big climactic moves when their player wants if you are modelling 4e
When translating into 5e, both Dailies and Encounters go into the same pool. The damage is handled separately because in 5e the damage scales automatically by means of Extra Attacks. Really, the 5e cantrips should have been handled the same way, with the Wizard gaining extra cantrip attacks at certain levels, instead of the auto-scaling. When the Fighter uses a cantrip, and here when the Knight/Warlord does, the cantrips are a normal attack that can be used per-turn, and the Knight applies the Extra Attack feature instead of the auto-scaling.
In 5e, a Fighter − including this Knight/Warlord archetype − goes ‘nova’ by spending action surges that can multiply the extra attacks.
So because damage-dealing is handled separately, the benefits of 4e Warlord powers are mainly granting actions to allies, plus powers that relate to move for allies, barrier against enemies, healing of morale, and detection. Some powers improve hit accuracy and add-or damage bonus.
Because of the nature of these powers, the Knight/Warlord maneuvers tend to be just as useful at high levels as they are at low levels. Very few powers need to be withheld until a higher level prerequisite. Most work fine in a way that is balanced at low levels, and continue to scale well becoming more potent in combo with other abilities yet still balancing at high levels.
Most of the time, in 5e, the ‘Daily’ power is moreorless the same thing as spending an action surge.
If there are any 4e powers whose significant effects need a translation into 5e, mention it.
