You post the guns from best (top) to worst (bottom), and divide it into three parts labeled "overpowered", "balanced", and "underpowered". Height takes priority over the label. I'd say from best to worst, they are:
...Heh heh, Just kidding. I'll try to make a Tier List, but some weapons will be on twice, (Example: PR with Spec, and PR without Spec) --- I'm Derpitimus. I forgot my password, and got locked out of my account.
Overpowered Carbonizer (With Lock-on) Hive Cannon (without lock-on) Phase Rifle (With all PR upgrades) SMAW (With any upgrades that affect it) SCAR (With both damage upgarades) Strike Rifle (With both damage upgardes) SPAS (With Stealth) Melee (With Improved Melee and Supercharged)
Balanced Widowmaker Turret SPAS USP TPC Launcher AR-C Eclipse Warp Pistol Shrieker Dark Star HVS45
Underpowered MP5KA4 Phase Rifle (Without Specialization or both Ballistics) Deatomizer Aegis Device Strike Rifle (Don't get me wrong, I mainly use the Strike Rifle) --- I'm Derpitimus. I forgot my password, and got locked out of my account.
Also, you just put the guns in with what perks they're most often used with, and then factor in their counters, ease of use, etc. So with the PR, you assume they have a full loadout, you assume a warpy has Capacitor, etc. --- "After this generation, Sony and Microsoft will have so much money they won't want to make any more consoles"-Michael Pachter
