Warning: Monsters can enter town

[Treesh]

And you can't attack from town anyways, so honestly the idea that could be an exploit by any sensible measure is a terrible joke. Not that we're even talking about kiting to town to exploit monsters in the first place for any legitimate purpose.

In beta, you couldn't use your skills in town. In live, you can. I can't tell you how many times I've ended up right clicking on a town NPC instead of left clicking and firing off whatever is on my right mouse button, although I couldn't tell you for sure if it's just graphical or actually firing now that I think about it.
