Design wise - Bangalore "devs haven't figured out how to buff her existing abilities, community wants something that can't be countered"
Role wise - Pathfinder "only recon who doesn't scan"
As a teammate - Octane/ OG path "most likely to run off from squadmates who can't keep up, or aren't even obligated to follow to an eventual 1v3"
Crypto is far from being the worst, he just just has high skillcap with a kit that can potentially make him less mobile in a game where "movement good, camping bad" is the mindset of the majority "it's not coincidence that Wattson and Rampart are also looked down upon."
p.s. I know this is late, but had the tab open
