Thats because i like to play TBL (Team battle league) our current only PvP content active, and it requires to be way more tankier than normal PvE.
Good damage is all about you being able to do content on normal maps around your level. Ex. lvl 300 and you can do quests on maps level up to 310 without taking too long to kill stuff or taking too much damage.
This game also has a different kind of investment on damage other than your weapon, the skills enhance attributes. My druid has a total of 160m silver invested on attributes, they come from either raw silver, event attribute tickets and daily TBL box also giving tickets.
And finally, i do enjoy the full SPR build. New maps spawn rate is insane high. Just setting up laima + zemyna + owls around allows for quite comfy farming without tanking myself that much damage now that Sterea is bugged. Barely use any potions thank to the sp pool and sp recovery, and Owls hitting the same as 3 tics of carnivory every second do help a lot too.
An example of what i mean.
