Maybe getting back into it

[Jsuit]

What's up! I used to play this game a ton a few years ago, I started at level cap 26 and ended at cap of 61 in 2016 I think. I redownloaded it for fun and am thinking of trying it again. I have a couple questions now though:
I don't know why, but out of my some 500 friends are all gone, did every single person delete me from their list, or is that a thing that happens now?
I have a lot of vanities that I want to sell for some cash to help and I'd assume are expensive (purple founders, nordr, etc.)but they aren't in the auction, can I get some price tips?
What is the best gear for a lv 61 warrior now? I currently am using dusk armor of potency and rend tail ring with some crap necklace because those are new and I bought a cheap one
Thanks for any help! If anyone wants to add me, my name is Jsuit in game and I'd really appreciate someone who can show me the ropes again in terms of the economy and meta.
