as a 450 engineer I'm delighted to see this in in the 3.2 ptr patch notes:
  • Potion Injectors now increase the amount
    gained by 25% when used by engineers. Quantity produced by recipes for
    Runic Healing and Mana Injectors has been increased.
  • Increased benefits from Hyperspeed Accelerators, Hand-Mounted Pyro Rocket and Reticulated Armor Webbing glove modifications.
nice

this looks like great patch all round - well for my team anyway
