What skills would you recommend for a Non T-Falcon.

I just got 2 Cormacs so I abadoned my two Falcon pilots and opted to start over. The two skills I had on my pilots were Mechanic and Armor Expert. Of the two, I really miss the Armor Expert. I'm running one of my Falcons as MR sniper with Dragoons, and the other with triple Avenger like you (or sometimes with Exodus), and the Armor Expert really helped the brawler Falcon.

Yeah I figured that both Avenger skills are a must.
This is good because it's more easy to move the pilot to other robots that can use Avengers as well (Natasha, Fury, Carnage).

I'm thinking in Sharpshooter, Speedshooter, Armor expert, Mechanic.
Make the Avenger as deadly as possible and the Falcon as durable as possible.

Depends what weapon load you have on. If tri-avenger/tri glory then shotgrouping is a must. Accelerate 50% faster is also good if triavengers. I run avenger two exodus so i only use avenger shotgrouping. If you run tricalamity get the faster lockon.

Second skill is wonderworker
Third is armor expert

If you really wanna go all out then:

Fourth is deft survivor
Fifth is raider mechanic
Sixth is adamant guardian
Seventh is invunerable raider

Non t falcons are tricky but it is better than t-falcon only when geared to burst someone down in 3-4 secs. Any other non burst setup t-falcon is better. Exodus is my primary side weapon choice since thats 250 k dmg in 4 secs plus the avenger. In some areas you can jump kill an ao jun if timed right, Triglory also works, tricalamity is ok, i dont like lockon stuff but it gives you range.

I use lockdown ammo instead of heal. The pilot skills deft survivor+wonder worker+raider mechanic combo gives amazing healing if you push hard for beacons.

Also non t falcons must learn the fadeaway jump, and the fake sideway jump, and the over the head on the other side jump, you use lots of burst corner splash dmg. Get good at it.

My second Falcon pilot has Mechanic, Road hog, and sharpshooter....I run 3x Avengers, now all L11 and it shreds like no ones business!

I have sharpshooter thunders and mechanic with Avenger on top. I think this is the base meta Falcon build. You could add more skills but.. I'm busy with too many hangars.

I use falcon with viper and exodus (T-falc destroyer and very fun!) So I know all about the fun normal falcon holds. Use mechanic and roadhog FOR SURE. Now adding the legendary pilots skill is insane so I would if I were you and then adding extra health for the rest.

So I guess the line up should be something like:
Mechanic
Roadhog
Armour Master
Legendary pilot
Sharpshooter
Choice
Choice

The last 2 are for if you either play beacon games then run the adamant healing skill and the one that adds more defence points. If you play the other game modes even a little bit then run module skills or damage boosting skills.

I would love to recommend exodus for the back wings if you have some! The amount of damage is disgusting and they fit his hit and run style with the fangs. I get at least 2 kills with mine on bad battles.

Hate falcons more than Ao Jun's and aries. At least they are killable.

Since you have both the skills, don’t bother w Exos. A quick glance at Wikia upgrade costs shows about the same amount of sliver to 12Mk2 all 3 of you Avengers as to 12Mk1 just 2 Exos. Once they’re spooled up, not that much lower DPS and much more flexible than Exos. 

That said, one of my fav builds was Ember w/ Exos.
