Get tired of keying in 400 over and over and over and over when farming... here's how not to.
Got to you first NPC or target that you are spaming...
key in the troops...
select hero...
send attack(s)
now click favorites
then click the X (not Ok)
then click on your next NPC or spam target.
repeat...
the key step to remember her is instead of exiting the march menu... click favorites then click X each time... there's a bit more clicking then normal... but at least you won't have to type in the troop amounts over and over...
