So since we're almost to a new Season, we've gotten our mid-Season patch and our new do the Operators stack up against each other? Have they balanced out a bit, or are we still looking at the same thing as before?
For my personal opinion I'm going to be using then same kinds of tiers you find in fighting games; S (God Tier), A (Excellent), B (Good), C (Average), D (Below Average), F (Exceptionally poor or broken).
While subjective of course, the variables I'm using to judge where on Operator ranks are; weapon effectiveness + ease of use, gadget effectiveness/usefulness, deployables, and situational viability (generally useful vs. only certain situations, viability on Objectives). I'm also assuming all Operators are being played by competent, skilled players, not newbs or scrubs.
S (God Tier)

  • Ashe
  • Hibana
  • Thatcher
  • Twitch
  • Jager
  • Valkyrie
  • Rook

A (Excellent) Tier

  • Thermite
  • Glaz
  • Buck
  • Sledge
  • Mute
  • Bandit
  • Doc
  • Mira

B (Good) Tier

  • Fuze (Without Shield)
  • Capitao
  • Smoke
  • Frost
  • Castle
  • Pulse

C (Average) Tier

  • Kapkan
  • Caveria
  • Jackal
  • Montagne
  • Blackbeard

D (Below Average) Tier

  • IQ
  • Echo

F Tier

  • Tachanka
  • Blitz

Reasoning for some placements;

  • Thermite - Hibana can open more and do it from a distance, putting her at less risk than Thermite. She also cannot be Bandit tricked.
  • Caveria - Noob stomper. Weapons tend to be underpowered vs. others, and she loses an exceptional amount of her power vs. coordinated teams.
  • Echo - Easily destroyed drone, neither weapon is terribly effective.
  • Glaz - Powerful since update, but still not good at playing OBJ as other Operators and is limited to a sniper rifle only.
  • IQ - Despite her recent buff, her weapons are still only equal to other Operators and her gadget is not useful enough to justify picking her.
  • Tachanka and Blitz - In a game all about mobility and peeking, man who must sit still to be effective is free kill. Blitz could rank higher, but broken hitbox and unreliable gadget make him feel if not actually be pretty useless.
  • Jackal - Not a BAD Operator, but not a cornerstone of the team nor as useful as some other options.
