You have a responsibility to make those decisions for her as her parent. Unless something really weird is going on you have neither the obligation nor the right to make those same decisions for me, or for anyone else (excluding sons/daughters) who plays the game.
So you’re of the opinion that you know better than anyone else what’s best for them? Hmm, ok.
Getting a little tired of pointing this out but the Borderlands franchise has always had OP gear that stands head and shoulders above everything else. There are still active threads on the relevant boards for the original game and surprise surprise they are not just talking about how much damage they are doing with the Hellfire. And this is a game that’s more than ten years old so I’m pretty sure that the “long term” will have been reached by now. People will initially gravitate to the best gear, sure, but while there will probably be a honeymoon period where that’s all you’ll see, after a while people will get naturally bored with using one or two things and will move on. These things have a tendency to self-police.
There’s even a recent example in BL3, where everyone was talking about the Anarchy when it came out but now there’s barely a whisper. Because people have moved on. We’re not all 7 year old kids who need other gamers to tell us what is best for us.
And finally, history has shown that GBX are completely and utterly clueless when it comes to nerfing stuff. Honestly, who uses the ion cannon now? It’s gone from a must have to a museum piece almost overnight. The 300/90 has gone from a must have to a must trash item. And why on earth did they bring an accuracy nerf to a weapon from a manufacturer who’s USP is their laser-like accuracy? You couldn’t make this stuff up. Calling for nerfs for things from GBX is effectively the same as lobotmising them. They don’t understand subtle.
