Raids

I'm just tossing out some basic ideals here, since it looks like Raids will be six man teams it seems we should be thinking about having two of each class on the Raid team. I know common sense right? But we have to think about sub-class within each one and deciding whom will play what role, a bit annoying at this point since we don't have full details of all the sub-classes for each class. But still all the same, now might be the best time for all of us to start thinking about what role we would like to play in the Raids and upon release date start working towards those goals and of course as more information is posted we can adjust as needed. I personally like playing a healer role and if the Warlock sticks true to that aspect I will most likely go with that, but on the other hand if the Titan continues to turn into the tank I think it will be then I will also consider that role as well. And as for the Hunter, it's just not my cup of tea. It's a cool class, but I prefer the other two. So even though it's early yet does anyone have any thoughts about how we should proceed?
