There is something seriously wrong with the drop rate of exotics and/or the rolls that you get. You wait ages for an exotic drop and then the perks end up being shocking. I have peacekeepers with no SMG perks, enhanced sniper dexterity and special ammo finder. I have actium war rig with unflinching bow aim and bow reserves. The obvious solution is to increase exotic drop rate, but Bungie want to keep exotic drops 'special', which is fine to some extent. However, the above exotic drops were far from special. Should all exotic armour be re-rollable through Xur? Perhaps limit this to one perk slot on each item, similarly to gear re-rolling in Division.
