These are false.
It isn’t supposed to.
5v5 is primarily about balancing Tanks and the synergy and incredible defensive power they create when paired.
Not necessarily true.
Largely because the developers came from an MMO-background and tried to create a situation where there was plenty of flexibility for players without considering the competitive aspects of the game. Simply put; Tanks are an anomaly in game-design. They don’t exist outside the MMO-sphere and they can largely break the game if their sole-purpose is to mitigate damage and/or be sponges for damage. Everything ends up having to be tweaked around them. Too high, and the rest of the roles suffer. Too low, and Tanks end up excelling where they shouldn’t be.
Now consider doubling up on the number of tanks allowed per team.
Symmetra is not a close-ranged character.
This is false.
Blizzard is more likely to know where the meta is going to shift than much of the playerbase does. Jeff Kaplan even predicted Brigitte was going to have a monumental shift in the metagame even before her release.
It’s clear that you’re not quite aware of how long and how much time it takes for patches and character design work to be done. And how much testing goes into that. And even should something break, they always have some back up solutions to try.
This is still anecdotal.
Folks, the 5v5 switch is not to address queue times. It specifically about balancing the game, not for any other reason.
What Blizzard plans to do about queue times is not entirely clear at the moment. Currently, OW1 has largely addressed the best they can with increasing population from console and introducing incentives.
With OW2, PvE will be a component to the game, and will very likely have a multiplayer-component. It also completely possible that much of the incoming population for OW2 will only play PvE. And it also completely within the realm of possibility that wait times for PvE will exist unless Blizzard does something like introducing bots to the gameplay.
Most of you are making rash judgments without an inch of evidence. I understand the concerns and I’m sure Blizzard does too. But you’re going to have to wait until Blizzard addresses those concerns.
