From my perspective,
Tanks should be more in line with “Heavies” from class based shooters, than Tanks from World of Warcraft and League of Legends.
I miss any "Tanks from FPS games"?
Pretty much the only way they get these queue times solved, is by making current DPS players actually want to play Tank instead of DPS.
Also tbh, I am toying with an idea of all heroes having out of combat regen.
But just minimal amounts for healers/DPS, and about 30hps for all Tanks.
