If you think about it, this is a direct way of balancing PvP loadouts. Remember Firebolt, Viking Funeral, and Touch of Flame? Wombo? Blink, Back Stab, Fleet Footed, and Hungering Blade? Add your weapon of choice and the forums would be full of tears. Everyone thinks this decision was for the casual players but, I believe this is to limit diversity and keep it controllable. Bungie has took it upon themselves to build a Guardian their way. So it works the way the intend it to be. It's their way of taking back what they created and making it more linear and controllable. PvP players wanted balance, they got what they wished for.
