In my opinion Boba Fett's rocket barrage only had to be nerfed in the damage it deals towards heroes, because the rocket barrage was only too overpowered against heroes and not reinforcements or the infantry classes. After the nerf of Boba Fett's rocket barrage it was very hard to get more than two kills in galactic assault with one rocket barrage. The "Triple Rocket Barrage" challenge, where you have to kill three enemies with one rocket barrage, looks almost impossible to complete. I have played long enough to play with Boba Fett's rocket barrage the right way and make some kills with it. However, while this challenge can only be completed in GA or HvV, makes it really hard to kill more than two enemies. In most situations there are not even three players standing next to each other and when they are one of them will most of the time be a reinforcement or a hero. Moreover, the heroes and reinforcements standing next to each other are mostly influenced by battle commands and therefore have a higher amount of health. With the nerfed rocket barrage it is impossible to kill this group of players within one rocket barrage ability use. My suggestion for the rocket barrage is to buff the overall damage again, but nerf or alter the star card "Anti-hero Rockets" which does increased damage towards heroes. I think the game is more balanced this way and it will be less hard to complete the "Triple Rocket Barrage" challenge. After months I still have not completed this challenge, because I cannot get myself in the right situation when playing Boba Fett to perform this triple kill with the rocket barrage. The possible scenarios in which this triple kill can be performed will increase when the overall damage of the rocket barrage also increases.
My second suggestion for this problem is to alter or delete the "Triple Rocket Barrage" challenge and make a new challenge out of it. For the reason that my biggest problem with Boba Fett's nerf is that I can almost not complete the "Triple Rocket Barrage" challenge I think it is the best idea to change the challenge instead of the buff and nerf suggestion that I gave previously.
I have posted this before in the topic "Why was Boba Fett nerfed He didn't need a nerf", see https://answers.ea.com/t5/Game-Information/Why-was-Boba-Fett-nerfed-He-didn-t-need-a-nerf/m-p/650393...

An other aspect of Boba Fett that I have noticed is that his health regenerates to a too low amount of health after Boba Fett nearly dies. For example, I played a match of heroes versus villians and Boba Fett got a high amount of damage that almost killed him, so I found shelter and Boba's health started to regenerate. His health regenerated to only something around 150 health points, which is the same amount of health as a officer. This makes Boba Fett extremely vulnerable for attacks even from the trooper classes. This is another aspect of Boba Fett that makes completing this challenge too hard. I have added a screenshot to provide evidence of this.

For the time being, my suggestion is that you try doing it on the Death Star, there are big groups of people in confined spaces in every phase on that map. Or Kashyyyk, before the second phase, clones always seem to gang up in the bushes before the Juggernauts, that's where I completed it - though long ago, pre-nerf.

@felker_s I have tried Kashyyyk so many times, because that map looks like the only map in my rotation. Unfortunately still no luck on that map. I have tried the Death Star map sometimes, but even then it looks impossible. Some other guy recommended me to try this on Yavin 4, so I tried that one also and as on the other maps I still cannot complete this challenge. I have had some good chances and many double kills, however a triple kill is too much to ask for. I hope my posts can get some recognition, in that way EA would maybe listen to my problem and probably that of many more players (especially the recently joined players).
@felker_s thank you for your reaction
