(Just prior to this, compares 3.5 and how the druid sucks at healing so you need 5 characters if someone wants to play a druid.)
James Wyatt: ... We've narrowed down the functions that each role performs, and designed different classes to fill each role equally.
GamerZero: So, for example, you can have a cleric, which is great, or you can have a druid who is different from the cleric, but can fill that primary role of being the primary healer in the group.
JW: Just as good. Right. And within that role, there is lots of flexibility. For example, two charcters designed to stand in the front line and hold back the monsters, the paladin and the fighter, are going to do that in very different ways. And also, any individual paladin is going to approach his role in different ways; you still have the flexibility to build your character the way you want ... (explains different ways paladin could perform).
GZ: So what are the four roles? Are there four?
JW: There are four.
GZ: So the tank ...
JW: Right, so the fighter and paladin are defenders, who are there to make sure the wizard doesn't get smushed; the cleric, and
GZ: Primary healer ...
JW: I read on EN World or our site this morning that there is a warlord class in the game, so that's the other "leader" ...
GZ: Really? So you go to EN World to find out what's going on in the game, huh?
JW: (Laughs.) Somebody, uh, was going through the videos of the presentation and pausing, looking at individual frames, and there was something in the character generator that showed the warlord, so there it is.
GZ: Excellent.
JW: So the wizard is what we are calling a controller. There are many ways to control the battlefield. One of them is to drop a fireball over there ...
GZ: So the wizard is a little more crowd control ...
JW: Right. And the rogue, or the ranger, are what we're calling strikers. Their job is to focus in on a target, and put as much damage in on that guy as possible, while moving around a lot more on the battlefield than the fighter or paladin are doing.
GZ: So their focus is kinda targets of opportunity and then really unleashing tremendous amounts of damage per second on the ...
JW: Sneak attack is the perfect example of how the rogue does that now.
GZ: Right, OK. And so all the classes in the game will fit into one of those four roles?
JW: Yes. We're experimenting with concepts that might bend that a little bit, but yeah. The thing is also that those roles really define what you do in combat. Outside of combat different classes are going to be ...
GZ: That's how you play the game, everybody's different, right? I mean, you know ...
JW: (Agreement). The ranger and the rogue are both doing the same thing in combat, but outside of combat they've got different focuses and different abilities.
GZ: Right. And maybe not even doing the same thing but sort of filling that same role. Somebody to put out that damage when you need it on the target.
JW: Exactly, yes. ...
(They go on to talk about Saga Edition, Bo9S being "sort of" earlier drafts of what we may eventually see.)
