Them reducing CC so Tanks don’t get chain-CC’d so much, them adding lots of new Tank & Support heroes to start catching up to the number of DPS heroes, and having better balance patches that shake up the meta more often would all help balance queue times quite nicely in 2-2-2.

But how do you make it so Tanks are popular, without making Compositions too durable?
