First off, I ****ing hate Java updates, it's been going on for an hour now.
Maria got what I wanted to say, I only add that you, as in the player, are sort of a lancer too.
What I meant with the Max Payne example: In DA, your character is your avatar, you choose her looks, gender, name, personality, decide where she goes, etc. In MP, you are given control of a predefined character (hell, at one point in 2, you control Mona, so there you have your lancer), Max chooses where to go next, what he says and so on. DA has every reason to call the player the hero, but MP doesn't (not that it wants to anyway).
Btw, aren't you a lancer in DA too at the beginning (and in the city elf origin a heroic bystander)? Isn't the focus at first on the king and Loghain, and you're sent off into that tower?
Yay, the update ****ing stopped.
