I was able to play some Zarya in comp last night. I don't think the nerf hit her too hard. I was still able to do 15k+ damage with her on about 50% average energy. I think the biggest nerf to her is the 25% ult increase. Zarya already had one of, if not the longest, ult charge rate, and now it just takes forever to get one graviton surge.
I also played D.Va in comp last night and she's definitely way more effective now (coming from someone who has 120+ hours on D.Va). The movement speed increase while shooting allows you to track enemies who are low on health more effectively, and the extra 100 health helps you escape when you are about to die.
