He's moving anyway, no matter if you snipe him only or if you're using explosives.

Use whatever primary you want. Black hammer and super good advice. That's all you need Watch this https://youtu.be/ZKU5jzDH4vI Please subscribe if it helped

Haven't ran VoG in a while, but I seem to recall him striding back and fourth regardless of what's being shot at him. Anyway, first off let's talk about his precision box - it's big. Second let's talk about ice breaker - you run out of bullets before times vengeance ends every time meaning you aren't maximizing damage output (or you are firing slow to maintain bullets but still, that's not maximizing damage either). Now let's talk about how many guardians own Gjallarhorn, I'd say at least half if not more - there's most likely 2 or more in each raid that own it. Last let's talk about heavy ammo, xur sells it we every weekend now and you get 5 for only 1 sc. So based off this hypothetical information (because I'm too lazy to find links and post for proof - you can search yourself if you care that much), at least 2 people should use Gjallarhorn and dump 6+ rockets first times vengeance. The other 3 should fire whatever heavy they have. Everyone should be using praedyth's revenge because of the fast reload, increased mag size, and high fire rate (if you don't have one, then use ice breaker but prefer everyone to use exotic heavies). Atheon should be dropped right after the 2nd times vengeance kicks in. And if you miss a sniper precision shot you are still doing 100% damage (vs I believe 150% for precision shots) so what like 7.5k vs 11.25k per shot or something - not a huge difference when you got 2 gjally's dumping 6 or 7 rockets. When ever raiding with randoms, the group should communicate and all decide on a strategy before tackling the raid. It saves the whole group time by not arguing over stupid things, booting people or people getting mad and leaving which means more time searching for another random, & it saves people from getting singled out usually. Be open and don't think that your way is the only way because I guarantee you, there is a group out there that can prove you wrong

Let the snipers black hammer him while other teammates are in the portal. When everyone comes out you can gjally him to death.

don't forget to throw all your grenades at Atheon too

My clan, for some reason, does this all of the time. There is always at least 1 or 2 that have to fire rockets. We almost never get him down in 2 rotations--normally takes 3 (or even 4 if 1-2 people somehow die). I'll then join another group of friends that I occasionally Raid with and we ALWAYS kill Atheon in 2 rotations (he's normally dead fairly early in the 2nd rotation)

Am I the only one who uses corrective measure at atheon for oracles

As in any team activity, the majority should rule. If everyone is wanting to use rockets and you're saying use snipers, swallow your damn pride and use a rocket. If everyone wants to use snipers, use snipers and put the rockets away. The collective team is what is accomplishing the mission. If you want to be an island, solo it. Otherwise, do what the team wants. Personally, I'm a fan of using snipers on Atheon. Less chance of blowing yourself up in a bubble.

You do not need to have any specific weapons for Atheon other than something to rapidly kill oracles. Requiring everyone to become a sniper just to accomodate one persons Black Hammer fixation is just as ridiculous as requiring everyone to have Gjallarhorn. You have up to five teleport phases before he enrages to kill him with whatever weapons you have, and people have even killed him on hard mode with nothing but Radiance and endless fusion grenades. The notion that everyone needs to snipe him or must trick his AI into not moving is nonsense. As for 'efficiency' the sniper bubble strategies can waste up to 1/3 of Time's Vengeance in total if you factor in all the seconds lost getting everyone to the center island, then seconds lost having everyone move in and out of Weapons of Light, then more lost while refreshing Weapons of Light, and then moving away from the island at 3 seconds remaining. Not to mention requiring the Relic Holder to adhere to a purely passive role instead of allowing them to actively damage Atheon when in a group that does not rely on precision damage or huddle strategies. Or everyone can use Gjallarhorn and kill him in 15 seconds after Time's Vengeance takes effect from wherever they are standing in the arena--no aim or passive relic holder required.
