Scion trickster 50% regen rates on DoT kill

Hello.

I specced into scion trickster, but it seems the regen doesn't proc.

The node gives:
50% recovery rate of life, mana, energy shield if you've killed an enemy affected by your damage over time recently.

After killing an enemy with either poison support, decay support or Death's Oath (not seen as DoT?), my life and mana regen do not change. My energy shield recharge rate does change.

Unless I'm missing something, this seems like a bug to me.

Are you just looking at tooltips or are you using a stopwatch to time it? It might not show up on the tooltip.

Just looking at the rates in the character screen under 'Defence'.

I'm using Death's Oath. With the 50% increased regen I should be able to regen through the 450chaos/s damage. I never seem to do though.

Without buff: 393.3 life regen/s (without 3 end charges)
After a kill I should have: 590 life regen/s plus the increase due to 3 end charges (not sure if it's calculated this way)

I have -27%chaos res, so 570 chaos/s? (not sure if it's calculated this way)

After a kill, my hp goes down instead of up. I haven't timed anything.

Thanks for answering, both of you! For some reason I though end. charges gave regen. Sorry about that.

If recovery rate is not shown in regen, but it works hidden, than I guess that settles it.

I'll try to unhide my chars if you're interested, but it's not really needed with given explanation.
