Definitely not, that's an exaggeration. Hawkmoon, Thorn and TLW got hit hard though.
With any HC- any weapon of any class for the moment, it seems like- you have to play to its strengths, and specifically its ideal threat range. Hawkmoon and Thorn used to compete waaaaay outside of their intention for HC range.
At launch Auto Rifles were competitive at sniper rifle range. Before 2.0, Hawkmoon and Thorn were competitive at sniper rifle range, and Auto Rifles weren't competitive at all.
Now, neither Auto Rifles nor Hand Cannons including Hawkmoon and Thorn are competitive at sniper rifle range and both are competitive at mid-to-close range.
Much as having my absolute favorite gun nerfed stings, I am of the opinion that this simply makes for better PvP overall.
