This is one of the best lists I've seen. So great job.
Adjustments I'd make:
Unbreakable tier 3 [It's a decent character, but so are quite a lot of tier 3; too many risks that are full combo punishable.]
Metallic tier 3 [Tremor without IA quakes or armor just isn't in the same league, its good but not tier 2]
Warrior tier 3 [This character is not trash at all. No character with a safe special that can safe armor after is trash.]
Sorceror tier 2 [He's super strong no doubt, but he isn't tier 1. Mainly due to his defense on knockdown.]
Demolition tier 1/2 [Shes super good, like the rest of tier 2. It's hard to judge a character when only Scar represents her at the highest level and everyone else falls short even before the nerfs; she has a one dimensional play style and can struggle without exceptional reload timings and spacing. For me tier 2.]
Lasher tier 2 [Jumping around spamming whips is fun until a character has the tools to stop it and then hes quite bland, A tier 1 character doesn't care too much about the opponents tools.]
Hellfire tier 1 [One of the few characters that can slow the pace of the game down, can't be zoned, wins in the air for full combo. Excellent cancel pressure and throw game, with a super solid d4 and a counterpoke check (aura) you're playing his game.]
Ethereal Tier 1 [Same as hellfire, controls the game. Its her mistakes that will make her lose and the opponents needs to take risks to open her up, which are usually in her favour, don't jump!]
Stunt double tier 3 [I hate what NRS did to cage but SD is ok. He has a dirty counterpoke game with clones up and fullscreen mid projectiles and armored wake-ups are good.]
Konjurer Tier 4 [If the facehugger didn't whiff on low profiles or jumps, this would be a decent character, no
character can be competitively viable when its tools don't work due to hitbox issues, randomness puts this character in the trash.]
Tigrar Fury (possible tier 2) [Great frame data, solid projectiles, good character.]
Cyrax Tier 2 [With tri-borgs toolset {backdash,111,F13,throw,run speed,anti-airs} and the threat of EX-SAW in the neutral he can cause some serious damage to the opponent. Devastating set-ups and THE best corner game in the current meta; you best have that breaker ready.]
Smoke Tier 1 [As with all tier 1 characters, you play his game. On knockdown you have to respect his wake-up game and he has a nice little vortex. B2 is one of THE best whiffs punishers/mids and add in his teleport cancel in the air (which can launch) and the cheap mix with a smoke screen. Hobart is the king of mix.]
Ronin Tier 1/2 [Great projectile - Excellent mid pressure - Safe air dash - Cancels - Decent mix. His wake-up game is what puts him out of tier 1 but that debatable, I'm on the fence.]
Hat trick tier 2 [Low pokes into specials, are cancer and this character embraces it with a passion. Ex hat-toss is underrated and the pressure he can create using it to stay plus is a strong mind game that the opponent has to respect. Great wake-up game and some decent set-ups.]
