Here's a problem that I have with the Warlord. Let's say that I am that archer artillery character. I am the best archer in the party. A master bowman. As a matter of fact I'm not just the best in the party, I am the best archer for hundreds of miles in any direction. Who does this second rate archer Warlord guy think he is calling out a shot like I would miss such an obvious opportunity? I'm the best at what I do and he should leave me to it!
It happens in the same way that a coach sees things their players don't - even though their players are far better at what they do than the coach is, or probably ever was.
It happens in the same way that snipers, when possible, prefer to use spotters.
Two sets of eyes are better than one. Two brains are better than one.
Nobody performs optimally all the time. If someone could, there'd be no need for a dice roll. We'd just determine the bonus a character gets - a quantification of their optimal performance - and compare it to a target number.
In sports, we'd never need to actually play a game. Just determine what everyone's optimal abilities are and run a simulation.
The D20 roll models the variability of people's focus, effort, and success - as well as external factors. The Warlord's assistance mitigates the effect of those factors by providing a bonus or some other mechanical representation.
Just like real-life...
What I don't understand is why people want a non-magic support character.
I can't answer for "people" - nobody can - but I can answer for me.
I want a class that can eliminate the need for the crutch of magic - the
deus ex machina of magic.
Why do we need magic, when people are capable of such extraordinary things on their own?
I want a class that allows one to play in-game, with characters similar to so many non-magic fictional/literary characters.
I want a class that models and utilizes the effects of leadership that I saw everyday - in real life - during my time in the military. (And I mean "Leadership", not "Authority"...)
I want a class that highlights the Magic of the human heart and mind, rather than burying it behind a wish-fulfillment mechanic.
I want my role playing to be more realistic...
