I made a separate guide on weapons for Mass Effect 1.
For Mass effect 2 I always used Carnifex pistol, Tempest SMG, Vindicator AR, Incisor SR. For shotguns, either Geth Plasma Shotgun on softer teammates like Tali, Jack. While Tougher ones like Jacob get Eviscerator. Unless they get their own "signature" weapon like Grunt or Legion.

Remember to ALWAYS switch Zaeed and Garrus to the Incisor sniper rifle. They perform amazing using it.

For Mass Effect 3 the Best weapons you can give a teammate is Typhoon AR, Hurricane SMG and for Shotguns again Probably Crusader, Wraith, Eviscerator, GPS seems weaker on teammates in third game. All with the Choke mod ofc.

I keep the builds in mind (and favorites): very good guide lines, especially when you are a bit overwhelmed with the powers, their meanings and uses...
Just missing 1 thing, the weapons associated with the builds. It is a synergy, and some weapons classified as "good" for some can really under-perform with a build, and some underdogs can unexpectedly shine.
Especially in Insanity (otherwise, it does not matter much).
What were the weapons used by each of them when you made this guide?

Now Aria, if you're a biotic, she's very strong. Otherwise not so much.
Flare is great, but not on her. her cooldown is 19.35 seconds which makes her use it very rarely. But if you take it as your bonus power? It's a little under 6 seconds.
Her most useful power is Rave, of course. Carnage and Lash aren't as powerful.
If you are a biotic, build the lash for biotic detonations and cooldown.
The lash is actually a very fun skill to use on biotic Shepard.

Honestly, I feel like Omega DLC characters abilities are weak, specifically in the DLC itself.
Generally speaking you want to max their passives, because the active skills all share cooldowns except Nyreen's Lift Grenade. The grenade however doesn't work very well as Nyreen starts with 0 grenades, even when you max them out, and IIRC she has none a few more times in the DLC.
Biotic Protector sounds cool, but in practice doesn't work that well, you want her to deal damage. So it's just leaves Incinerate and Overload and those abilities are already in the list.
Just give her a Typhoon.

What about one for Aria and Nyreen, of the Omega DLC in ME3

Because there's more than enough skill points in the first game, and teammates can be really strong with SR + Assassination when you set teammates skill use to Active. It goes for both Garrus and Ashley.

Why have Ashley have both assault rifles and sniper rifles at 12? Wouldn't you just want or the other at 12?

Give this man a Medal.
