In this video, I explain for Patch 1.2 how to avoid “false” procs for the Accelerator talent in the Assault Specialist (Pyrotech) tree for the Vanguard (Powertech) class.
Prior to 1.2, to apply a burn effect on a target within 10 meters, it made sense to use Ion Pulse (Flame Burst) instead of Incendiary Round (Incendiary Missile), because Ion Pulse delivered more damage in a shorter timeframe, cost less mana, applied a snare effect, and could trigger the Accelerator talent to make the subsequent High Impact Bolt (Rail Shot) free.
However, in Patch 1.2, an internal 6-sec cooldown was added to the Accelerator talent, so you want to trigger the proc only when your High Impact Bolt (Rail Shot) has been used and is on cooldown. Remember, even if your High Impact Bolt (Rail Shot) is not on cooldown, by using Ion Pulse (Flame Burst) or Stockstrike (Rocket Punch), you can trigger the Accelerator talent.
Therefore, in some cases you may want to open on a target with Incendiary Round (Incendiary Missile) on your target instead of Ion Pulse (Flame Burst).
Effective PVP gameplay of Assault Specialist (Pyrotech) requires getting the most mileage out of your cooldown resets for High Impact Bolt (Rail Shot), so this is a critical concept to get right.
Let me know if you have any questions.
