This could go 50/50, if blizzard release this patch they need to buff barriers and reduce the ultimate cost rate by ALOT.
Having 3 dps can reduce the times for dps queue, but will make games much more chaotic. Having 1 tank/one barrier instead of two means that ultimates will be faster as it’s easier to hit people. And having 3 dps doing their ultimates would honestly just wreck havoc on the enemy team.
I think 1-3-2 is a very good way to go, but I’m scared the community will be sick of dps and ask for unneeded nerfs to the dps.
