You can't change companion weapons or armour

Is it confirmed we can't just change just like their preset selected weapon? Like we can change Cora's shotgun but not give her a sniper rifle?

Yes. We can't even give Cora another shotgun.

The squad weapons scale with their level.

The armor isn't the huge issue as it never was before in me2 or me3.  The issue is being stuck with basic milky way weapons when there's an entire loot, modify, customize mechanic in place.  I personally will never use a sniper so naturally I would give my black widow or whatever sniper I build to my sniper squad mate.  Not possible anymore.

Also as a heads up Jim Sterling gave BOTW a 7 so it's no longer the highest rated game on Metacritic, Zelda fans responded by DDOSing his site, so maybe the fact that it's a Zelda game that people had to pay €400 to play (switch console plus game) helped people overlook some of it's flaws. And it does have flaws, for me it's degradable weapon system is far more annoying than not being able to customise how squadmates look in Mass Effect. 

It would be cool if squadmates had their own actually unique weapons, but seeing everyone walking around with avengers is just going to be cringy.

I believe a similar argument can be made for the word ‘iconic’. By now it really makes me both laugh and die a little inside when I see this word used by BioWare employees to cover for the blatant lack of features in Mass Effect: Andromeda. You cannot customize your companions to preserve ‘their iconic look’. You cannot even turn helmets off and on in Multiplayer, to preserve the ‘iconic look’. Peebee will always have her Hamburglar face paint, because it’s ‘a part of her iconic look’. And now we learn that our companions will not EVER (well, save for the cutscenes that belong to ‘iconic’ Avenger rifle and iconic Reverse Carnifex, of course!) change weapons and their damage will just scale with their level. Coupled with the dumb companion AI (that makes them lie and have awkward seizures for better part of the combat) and their main role as a combo setup/discharge machines one might ask why they even bothered with those characters being a part of your team rather than just be there in predefined setups during the course of the missions (it’s kind of the case for Loyalty missions anyway). Seems to me they’re there to display their iconic, immutable looks.

But ‘iconic’ is a status that is earned, not proclaimed. BioWare cannot make anything ‘iconic’. It’s up to the audience to decide what is iconic and what is not.

Really? Because I heard there isn't even that...or has someone clarified on that? 

So everyone is Varric from Dragon Age II?

Yes. And no annoying "having to craft / buy weapon upgrades to keep him viable" like in DAI. Nice.
