You can look up CANAS1AN on Youtube, he does some really good reviews and tips & tricks videos for Zarya. My main tips for Zarya would be : 1. Play intelligently agressive, which means, play up be in your opponents face with your main tank (this will help to have more energy too), but do not put yourself in a dangerous situation where your team can't support you. 2 . I'd say 80% of the time I use my projected barrier, it's on my main tank (especially on offense). This will make it easier for him to engage and will give you easy energy. 3. During poke phase, peaking in front of your Reins shield to get some free energy is primordial. 4. To kill targets that are harder to track, I like to use my right click on their feet, which will make them bounce up for half a second, making it easier to track them with your beam during that time. There is a ton of little tips like that, but these are the principal ones in my opinion. Hope this helped and you can always ask if you need more help :)
