Hi all. Starting this off saying I don't main tank. Mained WHM from ARR to mid-ShB, finished ShB w/BLM and RDM and ran through EW with RDM and RPR. I'm trying to get out of my comfort zone and put a tank in my list of main jobs.

PLD and GNB are at 80 with WAR in the 30's and DRK somewhere in the 60's. I still don't intend to main Tank but I'd like one to dedicate time to. I don't care about its damage, I really just want a job that's beefy and easy for more casual play. From my understanding: DRK is kinda squishy but high damage, GNB is pretty self-supportive with both heals and some mitigation, WAR is pure healing and PLD focuses more on mitigating/blocking.

I know all jobs are viable - but from tank mains, which of these is the hardest to kill in, say, dungeons? Which is easiest for someone whose dipping their toes in tanking?
