I am just returned to FFXIV and hit 60 yesterday. I farmed the crap out of the 60 dgns and got 2000 law and i170. I joined a Bismark group and we wiped 6 times. It was clearly a dps check. One guy said I was only at 650/ idk what that means, the 2 bards were at 685. I felt like my dps was a bit low but even so I spammed dots on both adds even with reflect. I saved my cooldowns for them and it was still not enough. Another guy said the online guide says 600 is enough (no clue what 600 means) and said theoretically we had enough dps. We limit break and still failed. I returned to the game wanting to play dps this time around, at 50 I was a full time healer. Did I make the mistake of gearing summoner? I really don't want to grind Law again, I am kinda burnt out atm.

Questions:

Who are the best dps classes atm?

Is smn pretty bad or mid tier?
