The average hellregial user has no thumbs meaning they cant aim for anything
I picked it up and went against other assault users and destroyed them especially when they were using the Hellregial, why you might ask well its really simple.
The Hellregial is a level 10 unlock for a reason it has a skill curve to it sure at first it might seem easy to use and op but its not for the average player it only does work up close like an smg should its recoil pattern makes it so getting kills at range requires a steady thumb.
I would get into 1v1 gunfights vs a hellie user at close to medium range and kill them before they could even take down half my health.
The issue lies within the weapon choices people have most players start out with a low recoil gun and therefore lack the necessary recoil control to use higher recoil guns. The Hellregial's recoil isnt terrible but for an experinced veteran like myself who uses the parabellum ribyroles and other moderate to high recoil weapons the hellregial is a laser beam in my hands where as in a 60 round mag it takes beginners 45 rounds to get two kills whereas I (an any other battlefield veteran) can get 6-7 kills in one mag
Frankly if you played bf4 youll know what im talking about my favorite weapon was the m249 and man did that thing kick like a donkey
Anyways the Hellregial is fine for now honestly I can see why people would choose it over the Riby cause of the ammo but imho the ribyroles and smg08 are more deadly in an experienced players hands then the Hellregial ever could be
