Quick and simple. Last patch only 1 person in group could proc an equipped poison at a time.
There was an internal 10 second cooldown till next person or same gets to proc it again.
Did they do away with this internal cooldown?
Example. 2 stam dps in group running damage health poison ix. Stam 1 procs there poison. Will stam 2 have to wait 10 seconds till theres has a chance to proc?
