DnD3 is not a perfect system, but it's not an inheritely broken either. It meets the goals it was designed for. Arguing which one is better is more broken makes no sense. Taking an example from your arguments, staying alive after a crossbow hit is not a misfeature, it's intended. It may be intolarable in a game based on a Lovecraft books, but can be desirable in another setting. You can survive a direct rocket hit in Doom. You can survive that in DRL too.
Saying all that, I personally don't really care what system is used (exact formula of dice roling is not even a secondary matter). Anticheese is the most active person in regard to the IRC game (at least when I am online), so it's quite naturally that choice is made by him as he is making the biggest part. He picked a thing he likes and is familiar with.
Kornel, no one disrespect your views, opinions or the thing you created, but should you bash people for doing the things the way they like, especially when you are keeping a distance?
