Well, they can balance faster, and maybe in OW2, they can preview characters in PVE.
Also I’m trying to come up with ways they could make balancing easier. Notably this idea dramatically simplifies barriertank and offtank design.
✅ Modified 1-3-2 that can be 1-1-2-2
For instance, they could release Mauga, without worry that you’ll get Roadhog+Mauga as your tank lineup.
Or release 3x more barrier tanks, without worry about Double Barrier interactions
