Hi
Role Queue is actually great for the game however the balance means it is terrible to play tank and support. While tanks and support have an incomparable queue time the reason for this is down to balance I would say for the most part.
The Nerf’s and Buff’s over the course of late 2018 and 2019 just propelled the game into an unbalanced mess. What patch changes specifically:
- Mei Buff’s
- Doomfist Buff’s
- Orisa Buff’s
- Reaper Buff’s
These were just out of the normal range of power for the game. Meaning everything has to be raised up to them… No just Nerf them don’t buff tracer. - Armor Nerf
This was mainly to address the Goat’s meta and it is now destroying Role Queue. Armor just feels like normal health Rein and Wiston just get destroyed by dps buffs and this change. As they relied on that portion of there health.
I like many others do not want this game to die because Developers are not listening to the informed community. Every streamer and every Pro say the same thing on how to balance and it just doesn’t happen.
- Balance from the top down listening to their input and the lower levels will feel like it is fair. (or can do their own thing)
- Consistency of output must be kept in mind too. (Moira)
I like many other love this game and just want it to be great. 
Hope to hear from the Dev team Soon ™.
