It's not that there is no pleasing some people. It's simply that people are bored stiff when people offer PRATTs that are the very first thing that people suggest when they try to create a warlord in 5e. Especially when it has been pointed out repeatedly in this thread that the Fighter is set up to be a martial DPR character and that is simply not the warlord. It's pretty well known why the fighter fails miserably as a warlord.
As a base fighter, and especially with the Champion archetype, a fighter is most definitely designed for DPR; but it is not restricted to that.
With non-damage dealing maneuvers, ones that are tactical or inspiration based, the main contributor to the fighter's DPR - specifically multiple attacks - becomes an action economy resource rather than a damage dealing mechanic. (@Hussar said the same thing)
What I don't understand though, is the people here talking about the Warlord are for the most part, very well versed in design aspects such as this.
This is why I wonder if there is another core reason...the one I mentioned earlier...that's truly at the heart of this.
I guess another possibility is simply that some are having trouble switching their paradigm; merely a mental block that keeps them from seeing the Fighter as nothing but a damage machine. Personally, I don't believe this is true simply because of the level of understanding in game mechanics presented by the most vocal in these discussions; but maybe that's my own inability to see past my paradigms...
