You need;
Rogue
Killing Spree
A mount
Its hard to explain so ill post a picture(yes in the picture the gates already destroyed but you can use this before the gates destroyed to kill there cannons and players before your supposed to)
if this doesnt work for you, don't cry, your doing it wrong and keep trying, try a different mount, bind killing spree to a different button eg mines bound to T
