I should note that micromanagement is to be done before the battle, which is basically just drawing up the ideal plan. That said, winning depends crucially on the team. Some teams are better than others and the elites tend to play together anyways.
That depends on whos calling the battle surely, in an alliance there are many town leaders if one calls id expect them to do the mails and set up etc, advise sure but do it for them no. People only learn if they do these things for themselves. All id expect to do if asked to lead the battle is exactly and only that. Ill work with whatever I have, or don't have, to the best the situation or set up allows.
As to the elites they do tend to group together I know, I would find it a pleasure leading a group such as that if only for the reason of working alongside experienced players would make leading that much easier but it wouldnt really be much of a challenge or make for good battles. My thrill comes from having average players take on these elites and beating them anyway. Of course theres only so much you can do if one side insists on tanking and all clubbing together all the time but that is a different issue and about balance rather than anything else and nothing to do with being a fort leader.
What a good battle leader can do is make an average team as good as any elite team led by an average leader. Your average team may not win very often but they will put the wind up those elites and make them pay for any mistakes given half a chance
Get two very good leaders with a balanced team on both sides and then you have the making of an epic battle. They are unfortunately rare these days since every other player is a tank and hp decides 90% of battles and the hit ratio.
One other thing, people constantly talk about fort builds when all they really mean is hp. only one thing is needed to be a good fort fighter, LOS the rest is all secondary apart from choosing dueler class but then that still dosnt mean your a good FF just because you get a few crits, thats down to LOS and the fact that the more shots you get off the more likely youll hit a crit ergo a better overall damage ratio.
Id say chuck that asking certain players to block etc isnt so much micromanaging as tweaking when needed and part of leading any battle im sure we all do that on a regular basis, ill also be exact on occasion like 3 steps down etc if the situation requires it or trying to keep a leash on things where timing is concerned. Overall a good battle leader will do what they do and not even analyse what they are doing or how they are doing it but rather just get on with it automatically.
