Hold on… might have found a bug here…
On the skills tree for Vengence, it said it was Level 20, but still had 20 skill points to be allocated… obviously I have had it maxed out since before 0.8.1b… but maybe something went wrong on the update and reset it but still showed it was maxed out… Tooltip dps has now jumped up to 12k… maybe thats what I was experiencing…
