Kotaku piece is kinda whatever. Some things right, some things wrong. They should call me next time they wanna talk about Overwatch
I will say "it's been like this since S2" is kinda misleading tho. The systems were the same, but it takes time for the symptoms to get worse and worse. Sometime in S4 it hit critical mass.
Edit: While I'm here, I do want to point out some shit about balance in the game rn. I've been thinking about it a lot and the game isn't /that/ unbalanced across the board. The extreme outliers at both ends are just causing some serious problems and have other design issues going on.
