I see, so tactics are anything more than
"just rush the weaklings and kill them!!"
Speaking of "commanders", some people are really role models and many players will give their (virtual) life for them, unfortunately most of the bossy players are kiddies or under-average players. Blending both on the battlefield confuse many players
Well, as sad as it is, but with the current level of cooperation on the servers everything which goes beyond "[W]-autowalker-lemming-Rambos" is tactics.
Don't forget that the game doesn't necessarily support the same tactics like in real life. While fighting shoulder to shoulder in RL is benefitial to protect each other, it doesn't work in cRPG. You would teamwound everyone around you, and you couldn't fight the enemy properly because you need footwork to move your body. Moral is also less important. It still matters, you often see it when a team gets literally steamrolled although they had the same preconditions, but in general people are less afraid to die and thus there is no routing. Cavalry attacks don't work the same way like in RL, because compared to RL horsemen are much more vulnerable.
This further reduces the amount of tactics which are viable ingame. I wrote already a few tactic guides in the newbie forum, and I think in the meanwhile those topics should be the last ones on the last forum page (they were some of the first to be written in this forum). And during all that time I learned only few things that I could add. Most stuff is really limited.
Concerning the matter of "leading" instead of only "commanding": I guess one factor I read somewhere about was, that your reflexes for online gaming are the best at the age of about 17. Then they will decrease a bit until middle/end of twenties, and then decrease faster. It definitely is not the only or the deciding factor, but as reflexes are important for such a skill based game like cRPG I guess it makes some sense. Especially if Bjord claims that the wannabe commanders are usually older, which could be an indicator that they try to gain success over their advantage (experience -> tactics) than disadvantage (worse reflexes).
It's only a theory though, and I can't confirm it as I never was a powergamer and thus can't speak from my own experience. And I am 26 already, so I'm on my way down already
