Semantics. I expressed my opinion and have moved on. From my experience, the MTAR-X was the strongest weapon in the SMG class, easily. And there is no denying it was heavily used in the CoD Championships.
Fact of the matter is, the weapon will matter far less than the player using it. If a player is more comfortable with say.. the Vector or CBMJS then they may have more success with it.
my opinion was that it was my fav and best of the smg class and i didn't even bother with any other smg... all i did was use the 3 attachment perk and add the red dot sight and the iron sight problem was solved... i didn't really need off the grid anyway as that perk is almost useless anymore... now i'm forced to use other smgs, ripper, bizon, vector, etc... i didn't even have over a 100 kills with any other smgs.
