Thorns: if they can't be viable, replace them?

Short version: thorns bad, fix thorns or get rid of the wasted nodes/armor slots.

Longer version: I love the idea of reflected damage, but with how much offense overwhelms defense, it's not viable to get hit in an attempt to reflect a negligible amount of damage.

Thorns could be useful if damage was a bit slower and everything didn't need to either immediately die or immediately kill you. Then the extra reflection could be relevant. The reflection would also need to scale (perhaps off the defensive stat of the item). And it would need to scale off of all hits without needing to sacrifice your hat slot to reflect all hits instead of just single target physical non-AoE melee hits.

Specifically, it would need to reflect when attacked, rather than when damaged so you can still thorn people while blocking or shielded.

Short of that, can we just delete the stat? Otherwise it will eventually end up on monsters and the people with out of control AoE will continually nuke themselves and be sad.
