Anet, seriously. Why aren't conjures used as ammo utilities? Engi's are living their best lives, swapping from Holo, grenade kit, elixer gun- going back and forth between melee to range. And here I am, trying to conjure a humble earth shield just to survive.
Ammo effects aren't buffs. It takes away the clumsy and clunky design of summoning a weapon that is needed at the moment, not 1-2 sec in the future. I don't believe the excuse that Ele has 25 skills, which compensates, is valid anymore. Not after POF powercreep like Firebrand or Holo. 25 Skills is cool, but not an advantage anymore in today's meta.
Change: Conjures are instant access by ammo. 2 ammo available on same CD as before. First click summons to your hand. If the Ele already has the conjure in hand, the second click activates another conjure at his location- Easy
