I love the destructible generic shapes and think they will enhance the gameplay and even give map creators some new ways to create things but I was dissapointed that all of the destructible generic shapes could be completely destroyed. We need generic shapes that do not get fully destroyed so for instance the major part of a wall will remain but a hole can be blown in it to shoot or crawl through. Also it would be great to have stairs that get partially destroyed but for the most part remain usable. I realize we can accomplish this with a combination of destructible and non-destructible shapes but it seems a no brainer to offer partially destructible generic shapes as well.
