Why are shotguns so bad? [RANT]

So right now I am playing Caveira and I am getting destroyed. Not because I get caught. BECAUSE MY SHOTGUN DOESNT ONE SHOT WHEN IM IN POINT BLANK RANGE SAME WITH PULSE. Shotguns have trash range. They are inconsistent. And are bad in general. I was in a 1v2 situation I was playing pulse and I already downed buck- thermite was still alive he proned, slowly peeked. I shot him in his head 3 times and he didnt die. He was pretty close as well. Please ubisoft buff shotguns, give them at least a slight headshot multiplier.

PS: Why didnt you shoot again? Because I wanted to interrogate him not kill him.
