Nobody should be banned for honest and proper criticism/opinion, or banned under a double standard/bias. Please exercise and defend your constitutionally and naturally protected rights, such as freedom of speech and the ability to challenge unjustifiable rule enforcement, no one else will do it for you. Thank you.
If you want to tell me I'm wrong, please prepare to tell me with logic.
Nope. Not always.
It depends on what is available and what's on the map. Assuming you already have a Battle Rifle or Carbine for your main weapon, you should only swap out your Assault Rifle for other weapons that serve a situational purpose depending on the map.
For instance, if I'm on Narrows, I'll swap the Assault Rifle for a Plasma Pistol and have a noob combo setup.
If I'm on Epitaph or Cold Storage though, I keep my Assault Rifle and use it within close radar range or whenever applicable.
Now, if you're on like Valhalla or something, then yes, swap it out.
Do remember that you should swap it for a power weapon such as Sniper, Rockets or Sword on any map, but that goes without saying.
