This refers only to tier 1. In no way am I suggesting any changes to any other tier.
IMO the only major change needed to balance tier 1 PvP is to fix the BO seats on the BoP to 1 tac, 1 eng and 1 sci.
In my experience BO powers are what determine the fight, and this is why the Miranda is inferior to the Tier 1 BoP.
The jack of all trades Miranda is no match for a more customisable BoP.
