I usually read the patch notes pretty thoroughly and I didn't see any mention of the Tri-focus passive for lightning staff changing from 7%/15% to 70%/110% Aoe damage for lightning staff attacks. Also, every tick spreads the AOE. IDK if it was like that before because I'm on xbox and just got damage numbers.
I'm really digging the changes but it would be nice to know that they were intended and will stay before I make my undaunted infiltrator set gold. Oh yeah, that set also buffs every tick.
Here's a short video showing the AOE damage in pvp before I get stomped on.
