Martyrdom was never fun in Call of Duty, and it’s even less fun in Dirty Bomb, since a HUGE part of the gameplay is melee-finishing downed bodies as soon as they go down to prevent an opportunity for a revive. Splash Damage should replace the Nader’s martyrdom with objective specialist.
Turrets were never fun in Team Fortress and they’re even more annoying in Dirty Bomb since there’s no way to turn invisible and stealth behind them for an easy disable. Splash Damage should replace the Bushwacker’s turrets with the ability to dress up like dead enemies if you stand over them and steal their uniform, just like the covert ops could in Wolfenstein: Enemy Territory.
