Has someone tried Bloodmage's Blood Barbs ? (Elemental hit damage counts for bleeding potency)

Hi.

I wanted to try it but it's going to cost me all my gold to respec and I risk bricking my character if it doesn't work.

Has anyone tried to build spell (I suppose Comet) bleed with it ? There's max 60% chance of bleeding in the tree, + 30% with the support + 15% for crits so it can be capped I guess.

If someone plays it or has seen a build using this I'd be happy to have some feedback, thanks.
