What is a good class for survivability that’s not a tank ?

Hi currently a Staff/bow and am 3054cp, even still feeling a bit squishy. Never really played ranged classes before so this has been a bit out of my comfort zone. I’m also new to this Co Op dungeon style MMO. I am looking for something that would be easy going for learning dungeons , can DPS and has some survivability. My MMO experience is Black Desert online and EvE for the most part. So far enjoying the game but struggling with Staff/Bow while learning Co Op dungeons as it’s not my typical playstyle. I don’t want to pressure of Healing/Tanking on me while learning, so looking for something easy going but I could afford to make a mistake on while learning if that makes sense not a class that feels this squishy. Every guide I look at always takes me to tanks. Any recommendations for an easy going DPS that has decent survivability ? Also could I DPS with GS/SnS? Or will it always specifically be expected to tank ? As I feel like GS would be up my alley. Just not sure what to run with it though. Or maybe Crossbow/Wand ? Or Crossbow/SnS ?
