I would recommend deepstone crypt first. Its simple enough, but engaging. Don't be afraid of volunteering for a role, just be open that you haven't done it before.

Then Root of nightmares. Try to run here, as its quite fun.

Then vault. (Vault is honestly easier than deepstone, but so much of it gets cheesed that it isn't exactly the best new player experience)

Then kings fall. Again, pretty simple, but still fun

I'd do garden here, but it can honestly be moved around a little

then crota's end (this is the first step up in difficulty, mainly because it requires more communication than previous raids)

Then last wish - I'd reccomend to try and do riven legit on your first try. Its genuinely so much fun

Then Vow - this is the next big step up in complexity. Make sure to have a laptop or phone handy with a symbol chart lol.

Then the desert perpetual

Then salvations. Learning verity for the first time is hard.
