You can, you just need to find the right groups. Communities and guilds are super helpful to get you started
Work on getting your ilvl up, do random pvp, pug some 2s, get conquest gear, do your weekly pvp quests for honor and conquest, pick a class that you really like the vanilla set for and read rbg guides on how the maps and your role work
It’s 100% a goal you can get if you work on it and put in the effort to socialize if you dont want to pug the entire way. Dragonflight will hopefully add new and returning blood to the pvp community as well
