I am only mid 30's on my vanguard, but I have already noticed that one of the main focuses is to setup Ionic Accelerator for a HIB proc.
This makes HIB more important than I first thought.
I have designated 3 points to spend in Shield Spec tree. I was planning on putting them into Intimidation, but now am not sure if 2 points in Brutal Impact would be of more benefit.
So +4% elemental damage vs 6% HIB, with the goal of setting up the best burst possible for pvp.
Are there any deep assault pvp's, who have tested both care to enlighten?
*Edit
I guess I have a second question, or more of a curiosity.
When IA procs a free HIB, do you still get 1 cell generated from High Friction Bolts?
