I’ve posted about this subject before.
I’m a fan of the concept, but not sure if the OW Team could properly rebalance the game fast enough for this type of change to be welcomed by the general community. They took nearly 6 months to get us to where we’re at now with 2/2/2 - which I don’t know anyone who suggested the idea would be good to implement without some type of balancing changes to go with it.
RQ is doing okay right now and is looking to get better with the next patch.
The game balance would need to be drastically altered in favor of Tanks to permit 1/3/2 to work with the added focus of Damage sources. I’ve seen fire-lanes that can instantly melt a Sigma from full shield to K.O. (Baptiste, genji, soldier, sigma, Roadhog, Moira combo on King’s Row) So combos that permit those damage lanes would need to be mitigated by a damage nerf or some type of survivability buff across the board for the Tank Role.
Maybe if the Devs made Tanks overpowered - more people might stop calling it a garbage role or a chore and actually want to play it.
