Sorry if this has been asked already, but how will you be able to choose character classes? As in how exactly will it happen, will it be just like CCR, or will you have to modify it in some way to make it work? Also, about the destruction animations, I see your point, but what about just making it so that there are destruction animations, but they don't effect the spawn points? For example, in the case of the power plant, you could have the tube thing collapse to one side of it, or maybe crumble in on itself, but not break any of the main structure or anything, but possibly have some holes in the wall, etc, but most of the debris flies outward, not inward, so it still looks cool but doesn't obstruct the spawn points. Something like that.
Once again, sorry if this has been asked/suggested before, but I'm in a bit of a hurry and don't really want to read everything....
