This mentality and these posts are bad for the health of the game. Stop asking for everything to be nerfed and instead your first question should be asking other players, maybe even the ones who play the weapon you struggle against, how to COUNTER it.
Perhaps even ask for buffs for other things to help counter it.
Even better, PLAY the weapon for a while yourself and learn their struggles and weaknesses.
Every build has struggles and counters.
Pick a weapon and someone out there struggles against it and thinks its broken.
-Someone who plays multiple builds and knows none of them are perfect.
