The official Battlefield Heroes site has a Q&A up exposing some more details about the upcoming free World War 2 shooter. Some of it further confirms the focus on casual gamers - it will be interesting to see if it has enough skill differentiation to enable the same sort of good competitive play that previous BF titles have had. Here's a snippet:

Will you be able to refill ammo/HP out in the field (as in BF1942 and BFV)? If not, will a class be able to hand out ammo/HP?

Every class in Battlefield Heroes has unlimited ammo and is able to heal themselves on the fly. Though the Soldier class could be described as being the closest to a traditional Battlefield ‘medic’ if you choose to play him as such; you could just as easily leave this group heal ability out and focus just on offensive abilities

Check out the full Q&A for the rest. We've got a bunch of screenshots if you haven't seen it before!
