I have never really killed them out of lock on range either. It's certainly easier with Sunspear. But usually I just get up next to them and roll and block. Before the nerf I just Iron skinned and ran in with combustion and great fireballs haha. I only started doing this in sen's when the tar pit alrady reduced my pace to a crawl.. Don't think Iron skin will do much for you now though. Better off rolling out of its attacks like everyone's saying.
A fun hint for killing the firt prowler in the tar pit in Sen's, you can do a plunging attack on him from the top, it stuns him too, so if you are using a heavy weapon you can pretty much kill him before he reacts.
