N7 Paladin should've had...

Incendiary glitching on PS3 is almost not a thing, whatever level your rattling excuse for a shotgun is at. You have to be in the land of frames on PC to see it to its full advantage. Big props to you for not liking the gun though. I absolutely hate it. But as for not reloading canceling on some kind of principle? I just don't understand that. As has been pointed out it's a deliberate design feature, and the way I rationalize its use is to remember that as soon as the chamber is full, I can do something else, so why wait around to fire the gun next while the animation plays out? With the Claymore in particular, this 'something else' often involves meleeing an enemy who might otherwise kill me if I have to wait to shoot him again. It's just common sense, and not some elite player half-cheat. If you want to become a better player it's a vital technique to fully embrace. 

On the Paladin, he's always the first of my N7 characters to complete his 10 extractions. Always. He's a delight to play, if, like me, you're generally listening to music while playing with the game muted. It's not his fault that Snap Freeze is stupid/OP/bugged/sounds horrible. He's not a Sentinel though. Tech Armour or Barrier instead of Energy Drain would have made more sense.
