This is basically what it looks like when the other teams are stacked. While the team I was on had issues with staying together, the flames literally just camped the spawn for the team and yes they were mostly DRK, BLM, SMN, SAM, oddly no dragoons, but warrior was there. The big thing was that the DRKs were always fishing out anyone with a lot of single target burst automatically and then just running off to do other things because everyone else will do the work for them. I can't do anything if I'm pulled into a mob and then cut up while the rest of the team is mindlessly running around getting mass CCed / AOE'ed while being constantly pushed into a corner. In fact, I think both the other teams basically just decided to troll adders.
I am literally on a freaking machinist with an LB and drill combo, and I can't even kill the BLM. He just double tanks two attacks meant to assassinate a single target because there is so much healing and so much cover from running around in the school of fish, that others can't even join in to finish the job. The only jobs that have any impact are ones that either fish or can do mass CC / Damage to a huge number of targets.
I'm sorry. A 3 man game where one team is basically at 70 points? Out of 700? With every team being literal 24 man raids it is not as simple as a player skill issue unless everyone just happens to be bad on that 24 man team and can't attack.
