[MCU] Why Won't the Avengers Travel Back to the Moment Before Thanos Atomized the Stones?

Well, it seems that it have been exactly 6 months after the release, or 7, so I don't have to put a spoiler warning here according to the rules. Several months ago, HISHE poked fun at this, when Youtube recommended this video to me again few days ago, I rewatched it and decided to ask people online. 

Why won't the Avengers just travel to the final stage of the Battle of Wakanda or the moment before Thanos atomized the stones? This way, Black Widow wouldn't have to die, and because Thanos would be killed, Tony wouldn't have to sacrifice himself because the gauntlet is completed (or nearly completed) at this point, they can have all 6 stones in one go. Thanos would also be without his army, armor, and sword, and if the Avengers decided to travel back after the first snap, Thanos would most likely be too weak to win in a fight against the Avengers - if anything, they could probably talk their alternate selves into fighting Thanos, doubling their manpower. Is this a simple plot hole or there's justification for the Avengers to go with this decision?

Too risky. Fighting a fully armed Thanos is a massive gamble that they lost the first time around. All it takes is for him to recognize the attack and close his fist and they probably lose. It's much safer to travel back in time where they can grab the stones with as little resistance as possible. And even that was risky, as someone ended up dead and they brought Thanos to the future.
