Juju, yes, I could probably adapt the system to make destructible terrain possible. But there's an issue. Leaving the terrain objects as primitives will slow things down due to the complex drawing and collision detection. Also, the primitives have as few of points as possible, to keep sending maps over the net lightweight. So it would kill the FPS in more way than one.

I seriously considered going with polygon collision detection, but opted against it. As it is, this game is going to take a very long time to develop. If I had to handle a custom collision system for every little object that would just delay things that much more. Call it laziness maybe, but I just didn't want the hassle.

Thank you TDOT. That's just a demo level I've put together. The final levels should look even better once I make them a bit bigger and add more textures and objects.

Evilish, indeed, destructible terrain in a quick paced online game like this would be a nightmare. Not only would it have to be kept synced, it could also introduce some very negative gameplay aspects when people start changing the level in real time. The gameplay hasn't been designed to allow for DT, so I'm not going to even toy with it.

Thanks for the feedback guys! It's always encouraging to get a good reaction to a project.
