How about this: an Exotic Sparrow with the following: -130 Durability -Same speed -Holding LT and RT for a short time charges a Blink (teleport) activated on release (uses entire Boost meter). -Holding RT while airborne for a short time charges a shockwave that activates on landing and deals damage to anything within its radius (the longer the trigger is held while airborne, the more damage and radius, costs up to the entire meter). -Double-tapping LB and RB at the same time generates a brief Solar shield around the Sparrow (at the cost of half the Boost meter), increasing durability and damage dealt to enemies from colliding with them. Frequently causes a burn after-effect. Acquisition: Rarely from Nightfall, Extremely rarely dropped from Crota or Atheon. Perks are acquired unlike other Sparrows, they are ready to be purchased (like perks on armor or weapons), but cost 6,000 Glimmer each. Just an idea, let me know if you like it :)
