Well... Templars kill guards too. Not forgetting like Haytham, Cormac will have a set of skills unlike standard Templars. Like Il Lupo and Vali cel Tradat he is an Assassin hunter. All 3 used Assassin skill sets to get them.

I DO see what you're saying... But not all Templars can be leaders of armies, and so can therefore use them. Some are more Incog-styled, and have to do some Guard stabbing of their own.
