Adjudicator not good?

I’m not saying it is bad fundamentally but I’m more of just confused. The adjudicator looks cool and on paper seems like it be pretty great. But in actually using on all fronts, it doesn’t feel all that great, I feel any job the adjudicator can do, the liberator pen can do better. I’d even use the standard liberator over the adjudicator. It always seems like I need to use almost a full mag to kill an enemy medium type of enemy. So is it only me? I’m just not impressed by it and I feel it should be better
