If you want to make a level 60 warrior, don’t let that stop you. Warriors aren’t necessarily great at all open-world or 1v1 situations, but Arms is pretty good in PvP now generally. You may take some deaths, but anyone can get pounded down pretty quick these days, so it’s not a big deal. I think it’s pretty fun.
I don’t really duel that much, but it seems like most of the 1v1 encounters I see in PvP these days are pretty quick burst-offs. Warrior has some disadvantages there, but if you can disrupt them and get up in their face, you’ve got an okay shot. I’ve been winning a lot of those jousts that I might not have expected.
There are some options for survivability or self-healing. Second Wind and Impending Victory can both help out if you can use them well, and I know there’s a Night Fae conduit that gives you healing while your in Soulshape. There are probably others. Ignore Pain, while costly, is pretty nice in a lot of situations, and is now baseline.
