While getting stacks yesterday on MP10 with mentok/yoyo/ammostiel, I was solo hammering a those exploding fat blobs in ACT 1 with Shielding and Reflect Damage when I noticed a kind of unfair mechanic (maybe a bug) -- when I hammer at a shielded blob, it's immune to my dps (obvious). But the interesting part is that it still reflects damage back to me. So net, I don't get any life steal and all the reflected damage.. had to actually play smart and fight the unshielded ones (what? I can't just smash blindly???).

That's exactly how it's intended to work as far as I'm aware! They're kind of a bitch.

This makes me think of a monk with thorns pop his serenity while fighting against Vampiric minions.
