I want a Templar similar to this man in DA2 -

He looks badass!
But yes, it seems that the templars are based loosely on the Knight orders of the Middle Ages, though there are many differences, for example the Knight Templars were pretty much sovereign, while the Templars of Thedas have to follow the Chantry rules and are supervised by the Seekers. There are many more, but I disgress.
Thing is, with the new approval system you won't have to like or always agree with a templar companion, if you don't like them at all, but you could have some sort of rivalry with them. I would like to see that.
