You can't change companion weapons or armour

I don't care about the weapons...whatever, it's cool.

I was hoping for DA:I kinda thing for Armor...or at least like they did it in ME3 where every squadmember could wear a proper hardsuit.

So in the Kit blogs for the characters they were releasing, in the part that says "favorite weapon" they meant literally fav weapon, because that's the only one they're gonna be using in the entire game.

We have only hope that moders will do something about that in future

I can deal with not being able to change companions armor but not being able to change their weapon... ah, man, that sucks.

Maybe you should actually ya know wait for the game to be released. It could blow you away. 

while armor is disapointing but me 2 and 3 didn't have much without dlc/mods anyway. and really as long as the appearance dlcs are cheap I don't mind paying for em.

and weapons I can think of a few good reasons why, starting with how some weapons had drawbacks that didn't affect npcs which included squadmates and the dlc weapons in me 2 were unaffected by the damage reduction sqaudmates got on higher difficulties, both can mess up the diffculty curve which can reduce enjoyment for some people. locked weapons avoids both those things. and it keeps people from wasting high value mods and augments that don't help npcs much.

Is stupid to me have that much customization and research options only for main character

Even in ME3 without DLC we still had a couple of options for each character, including something that at least looked like armor.

My guess is their kits are tailor made for certain weapons only.

So Drack using a shotgun with his kit, hes a close up bruiser by all accounts, so it does make sense vs a sniper rifle.

As far as not changing out weapons...my guess is because of the crafting mechanics.

Very good point. I guess I'm gonna research only the weapons my Rider uses. And the 1-2 weapons used by my favorite squad mates I guess?
Anyways, looks like a lost opportunity.

Is there any possible chance that the reason we cannot change squadmates' weapons because we can modify them so heavily? Could it be that the squadmate AI is just not advanced enough to be able to deal with the difference between a shotgun with laser shells, ME1-type overheating mechanic, heat-seeking plasma rounds, etc? It could be that in giving us the PC more choices that they had to limit choices for the squadmates.
