Indeed:
DRG = Dragoon disappeared? Spread/heal/guard. Or simply sprint away, the dragoon can die from dots while in the air and the only thing they bring to the table is damage, so nerfing their lb would make the class worthless in any comp. Is pvp as you said you aren't suppose to have a pve indicator so everyone can just ignore the LB.

Sam annoyed me day 1, now I either CC the Sam, spread away from team mates while the lb is ready or just focus melt them down.

Meanwhile machinist brings CC, dots, burst damage and a heavy damage lb and point support while being range and stupidly safe to play.

I feel all you need is more experience countering said jobs. The new pvp system is quite new after all.
