The one negative i can think of is the sheer time commitment involved.
Though my daoc leadershiop has had mostly positive affects. My virtual and
real life leaderhip have a sort of synergy - i learn from the two to make
both better.
If you have alts that take up leadership, do
you find that followers treat you differently when they don't know
it's "you"?
Whenever leading i allways go on my main character; Delivis. Name
ascociation is very important; if a raid is lead by a person people know,
like or think does raids well/successfully they are more likely to go on
that raid/event. The one great thing about alts is no tell hell
though..:)..not to mention no begging to run raids..or even bribing lol.
