Stolen shamelessly from various sites, I've made a list of little hints and tips I didn't know about that may or may not come in handy.
Feel free to add your own finds as every little helps!
Pharah:- When using jetpack, releasing shift and then holding it down again while on cooldown will activate it immediately when available. Could be useful in aggressive firefight situations.
- Landing after using jetpack (when hover mode not used) causes splash damage to nearby enemies. Useful for turrets etc? (UNCONFIRMED)
Genji:- Genji can technically triple jump. If you double jump onto a wall or object and then wall run you can jump a further one time. Good mobility for certain map scenarios.
- Deflect IS headshot specific. When using deflect, try and aim for the enemies head as it does make a difference.
- Visit http://www.furiouspaul.com/overwatch/genji.html to see what attacks Genji can deflect. You might be surprised.
Torbjorn:- When using Torbjorn's ultimate, Molten Core, if you don't have a turret deployed, do it now. Although a turret has to be level 2 to get the free upgrade, the time taken to upgrade a turret from level 1 to level 2 is HALVED.
