Hardest thing is probably Soul Ash and gearing though honestly you can get “decent” pretty fast through your covenant campaign and simply having your alt farm honor before you ding 60. Renown goes up fast.
The issue is once you get around 200 ilevel you can do PVE for some gear to compete in PVP or you can do rated and generally get stomped even in low ratings or as Oozo mentioned , RBGS.
The other option is to pick a class where you can excel and do decently against classes even if you are significantly outgeared
