Collision Detection

[Reika]

See, the people at Age of Conan have the right idea. They recognise a good feature but also recognise the flaw in the feature. So they keep the feature but solve the flaw.

At SE, it's just a case of flat-out discarding any feature with problems (e.g., mob behaviours, active combat, collision detection, repair materials).

And you know the main reason why they changed? Players.
