4 poison runeword for barb is broken

For anybody playing poison throw barb that saw the shield as a potential upgrade, DONT MAKE IT.
It effectively halved my poison duration, pretty much killing my dps.

1 snake bite to a TA miniboss around 80% dmg with a TU shield.
1 snake bite with the "upgraded" shield, around 40% dmg.
Also, spamming doesnt seem to work properly anymore, it doesn't seem to refresh until the poison completely wears off.

The poison duration from the poison runes seems to be screwing with snake stance because my stampede got affected aswell.

TLDR; dont bother till they fix poison runes.

whats happening there is it counts as 4 sources of poison damage instead of one
and thus in formula that counts poison duration there is division, and duration is lowered (by a lot)
dps stays same though

Is this intended? Or fixable?

I had thought it's an upgrade a few seasons ago when I tried to make a snake stance thrower and was thinking i just didn't calculate something properly, oh well good to know it wasn't me :flip:

The sad truth is that the poison runes are just really bad. The 1 second duration hurts them and they just don't add enough flat damage/second to keep up with the big sources of poison (like snake stance, amatoxin, and curare). Not to mention snakebite, which is probably over the top at the moment.

Maybe if the poison runes had a long duration but low damage they would be interesting due to how poison duration is calculated.

I think it would be interesting to see a SU or runeword with a modifier like "Apply 25% of poison damage immediately on hit". I don't know the exact numbers that would work. But that would be a interesting way to radically change the playstyle using an item. The item can be super hard to get like a SSU or SSSU.
