What are the "weights" of the different Heroes in Overwatch, and which abilities are impacted by this attribute?

Solution 1:

After some testing (my plays.tv didn't record because I had two clients open simultaneously), it appears as though character weight does NOT affect the knockback of at least Pharah's Concussive Blast.

I tested every character vs Pharah, every single character (exceptions below) are equally affected by the knockback, regardless of character model. This includes Primal Rage Winston and Tank Configuration Bastion.

The following characters are not affected by knockbacks under the noted circumstances:

• Mei (Ice Block)

• Bastion (Sentry configuration). He can still be broken out of Sentry configuration via stuns (Roadghog's Chain Hook, Reinhardt's Charge)

• Reinhardt (Shielding)

I can re-record these segments at a later date if video (or gif) evidence is required for the answer, then update accordingly.

!!SCIENCE!!

Testing information:

I conducted this test in King's Row, with the Defender being the class to knockback (Pharah and Lucio), and the Attacker being the class to get knocked back. To the left of the Attacking spawn (from Attacker's PoV), there is a manhole cover near a phone booth. The defender stood on the manhole, with a spray placed the same distance as the phone booth for the Attacker to stand on. The knockback direction went horizontally across the Attacking spawn. This ground provided a long, flat surface with no ceiling in order to keep the knockback as unaffected as possible.
