buffed: Let's talk about scenarios. I think the original announcement was that scenarios would be designed for up to 25 players. But all current scenarios are three player ones. Will we see scenarios for larger groups in the future or are scenarios always going to be three player content?
Street: We still like the idea of having some scenarios that are much larger. It just worked out that the ones we developed for launch all felt like they would make more sense for three players. If we did larger ones we'd want them to be much more epic -- maybe larger maps, maybe letting the group split up into smaller parties.

That's good to know, but by 3-boxing he can do all the scenarios with just his one group rather than having to split up into a 3-man and a 2-man (e.g. 5-boxing).
