So.. you only biosplode bosses. Ok.. that's uber boring.
When do you find room for melee? When do you Barrier Blast? Is your cooldown low enough to get a biotic explosion off of a Barrier prime?
There's all the nuances that make him special.. and almost all of them don't synergize with that using the PPR. Yet AGAIN you have taken a kit with a cool, individual skillset and turned it into another PPR or Claymore weapon platform.
What if I tell you that what is boring for you is not always boring for others?
The OP asks what is a suitable weapon for krodept, I suggested ppr. That's it. He didn't ask "how to play krodept kit".
Now you compare ppr w reeger.
What do you think about lolcolyte? Does one play the kit if he uses lolcolyte+hurrdurr on him? What does your "how to play the kit properly" handbook tells you?
