The fix for exotics would be to counter the weapons with armor. Such as an exotic helm form any class should have a slight increase to armor when damage is inflicted by any primary weapon that is Hip Fired. Or a counter to MIDA without ruining the weapon would be high caliber rounds fired from a primary weapon has a slight chance to stagger when an exotic chest piece is equipped, once staggered the armor piece increases agility for a brief moment to allow evasion. Another good one is Thorn, when an exotic arm piece is equipped and DOT occurs from a primary weapon, melee and grenade recharge rapidly as well as a brief moment of agility boost. This gives the player a chance to counter a gun fight with a grenade or melee as well as added speed. It's the simple things that should counter an exotic weapon. Leave exotic weapons un-nerf and buff exotic armor. Every exotic weapon should have a counter and it should be exotic armor. Let PvP become more of a chest game when exotics come into play. That way nothing gets touched in PvE.
