I suspect that drummers will replace Jannisaries, papal guards, captains and brutes in terms of morality. Earlier you had to kill a high leveled enemy to scare the others away. Killing drummers will be an easy way of scaring enemies so I suspect that they will run away or something and call for help if you do not kill them in time so as to make it more challenging.
