At this Point Frontline is done.

SAM is cringe but it's even more cringe seeing 5 people dropping to the most telegraphed Zantetsuken in the world. If you're a job with a shield put it up and bait it on you outside of your group of people who are clearly mentally AFK. Then /laugh and /sweep the SAM.
If there is no coordination from the other side (most cases on EU/NA) you can flash guard and run away instantly. DRK alone can't kill anyone but maybe one ranged that doesn't have recup bound, it needs other hard hitting LBs, guard breaks or just coordination in general in that tight window where everyone is packed up (as MCH I like dropping turret then either Bio or CS on everyone). I agree it's an issue on JP DCs though. At that point it's just awareness and preventively backing off if you sense a DRK murderblob approaching, and then just wait for your chance to counterpinch the DRK murderblob back.
Assfuck NINs with blota, but they really should down the strength of their shield. It gets way too big at BH5.
SMN has Aegis (amazing) and great aoe damage outside of Bahamut.
Warrior is a tank, and it's also mega squishy outside of LB (FL DR aside but that goes for all melee) once they've used up CC. You can't solo anything in FL, you need a group at all times.
BRD LB is the Spire, it's great.
SGE is good and has literally only one skill that needs to be cast, just like RDM it's just hard to perform well with.

I have no idea why I responded seriously on the official forums I'm going back to sleep.
