More, advance Ao Jun tips please?

What is your primary expected target for this Ao Jun?  There are generally 2 purposes of AJs out there now.  Titan killers and Ao Jun (stealth) hunters.

If you want a Titan killer, the generally accepted best load outs are Glacier and Ember with Avengers coming behind those.  The reason why is that the first 2 bypass physical shields and are great for the slow Arthurs out there (they do well on Kids too) and are passable on Mings and Nodens.  Avengers still put out lots of damage and do 2x damage on Arthur shields, but don't bypass.  For pilots, if you are planning to use a Legendary Pilot, the Alika and Adrian pilots work very well here as they maximize damage output.

If you want an Ao Jun hunter, then the first thing we are talking about is getting Yang Lee pilot that grants you Quantum Radar when in flight.  This is a huge advantage and will make you extremely dangerous to anything that can stealth.  The optimal load outs here are Calamity, Redeemer, Viper and Avenger.  These all can do significant damage and are relatively accurate.  Accuracy is super important with this as you're targeting fast moving stealth targets like the Loki and Ao Jun in flight.  Doing this while flying can be difficult.  The Calamity doesn't miss which is why it's the top choice.  Redeemer is also extremely accurate, though aiming is more difficult because there isn't a lock-on feature like with the Calamity and your range is limited.  Still, they hit like a Mack truck.  Viper is very accurate up to 400 meters and has the added benefits of being cheaper to upgrade and good against bots with DR (including titans, though not the Arthur).  They aren't the best for hunting AJs though because you want to kill them ASAP.  Avengers are less accurate than before, but are still a good and cheap option for sure.

I'm sure I missed something weapons-wise, but modules should be damage focused.  If played right, you should be landing in relative safety after flight.  Last Stand is good of course.  Lockdown Ammo and Deathmark are good Titan killing options.  Lockdown Ammo, Phase Shift and healing are probably good options for Ao Jun hunters as well, but I don't run the stealth hunters.  I'll leave that to other commentators.  I'll also leave good flight technique to others as well.  Much has already been said and written about this on the forums so the search function might also yield you good results.  Good luck!

Edit: I'll echo what ⓣⓡⓘⓒⓚⓨ48 said above.

Recent thread on this same subject. In fact, very recent and helpful: war-robots-forum.freeforums.net/thread/40688/first-ao-jun-tipps-needed

Wow!! Thanks guys!!! I didn't expect that much of a response!

Ive got 2 Glaciers and 2 Calamities, so I'm probably gonna try 'em out first to see which suits me most.
I dont have Yang yet, but i'm gonna try get it sometime later.

In your opinion, whats the biggest threat to an Ao Jun?
And whats the best things to use in high-meta leagues?

Thanks everyone!!!

Both Glacier and Calamity are good against Ravana, you just have to time it better with the rockets. Glacier is also much better against Arthurs. Calamity, not so much unless you can get behind it. You really can't go wrong with either build, but if you go Calamity, you should get the Legendary Pilot to go with it so you can smoke other AJs.

Also I would recommend PS as that seems to works best with Ao Jun, especially as someone new to flying the Ao Jun. It's like a get out of jail free card for when you land wrong.

The upcoming Quantum Radar module for Titans will be a huge nerf to the Ao Jun. With a range of 350m, that would mean you won't be able to use all the good anti-Titan builds on the Ao Jun. At this stage in the game, I'd recommend Yang Li and Calamities and playing the Ao Jun as a multi-role/range bot.

Is it really going to be released though? Also I heard Adrian Chong say that Ao Ming isn't gonna get the Quantum Radar, so if thats true, at least i can still smoke the Mings out of the sky. (lol)   

Since i hate titans and i want my Jun to slay them, Im upgrading my Glaciers now to lv5/6 so they can be fully usable when i get it.

welcome to the Forum!!

Ao Jun tips? just point and Shoot the Bot is Easy Mode for the Game that is the reason a Eschew that Bot altogether and Yes i have one(had one Since the Event that they 1st Dropped).it is just Gathering Dust in my Hanagar and i Doubt i'll ever use it Again since using a Ao Guang of Ao Quin is more Challenging to Play.
