Heya!
I would love to hear some of your Overwatch 2 Hero Talents ideas! 
I think a nice Talent for Sigma would be,
when Sigma uses Kinetic Grasp, all his teammates get a Kinetic Grasp as well in from of them!
Let me know your ideas for any hero
Cheers Love
Sure, I’ll share some ideas:
Doomfist: The Best Offense:
The more shield health you have as Doom, the more damage your abilities will do.
Genji: Shimada Instincts:
Deflect now deflects everything in a 360° area instead of just in front of Genji.
Echo: True Beam
When targets are below 25% of their health, the Focusing Beams becomes green instead of purple and deals 400 dps instead of 200.
Zenyatta: Orb of gratitude
Zen has a special Orb on him that will keep healing him all match for 20hps.
I have more ideas in mind, but i’ll end it there.
For Reaper, I was thinking of a talent that gives his team lifesteal. It is boring and not flashy, but your teammates would appreciate it greatly.
Widowmaker Talent: Charge rate increase to where 100% charge is near instant (Widow needs tons of buffs to be even decent in PvE).
Echo Talent: The player you duplicate also gets the same ult charge increase you get.
oooh, I like that one!
Symmetra: defensive wall
Enemies passing through the photon wall take damage and slow down as their hitbox touches the wall.
Moira: scientific absorption
the moira ray has a larger area and absorbs the life essence of many more opponents
Orisa: ride
during the fortification, orisa moves very fast, overwhelming the opponents she encounters (similar to d.va/soldier dash)
junkrat: rocket
as in heroes of the storm, junkrat rides a rocket that overwhelms enemies
Wow, I love all of the talents you have said
Winston: Power Pack
The longer Winston’s airtime is with Jump Pack, the greater his impact damage is upon landing near an enemy.
Torbjörn: Tinkerer’s Touch
For every ten final blows Torbjörn’s turret secures, it will enter its Overloaded state, firing rockets and having a much faster rate of fire.
Hammond: Piledrive now squishes enemies hammond lands on! 
Sombra:
Echo - Multiply
For each kills she gets as a clone, 1 second gets added to the duplicate timer
up to a maximum of 25 seconds.
Mercy - Combination
While holding both the heal and damage boost buttons (M1+M2) , a combination of these beams will appear , giving ,the target you’re locked on, reduced damage boost (20 % ) + reduced healing ( 50 HPS )
Not specifically a talent, but I’d want Brigs armor overheal to come back as a “Notable Co-op change”
