All I have to say to the people having trouble: learn combo fields, time dodges, learn mechanics, time dodges, condition removal skills, time dodges, and for some fights a stun break or 2.
All the old MMO ‘veterans’ who think they can go into a dungeon, have run into a group of trash and just tank / dps away by mashing skills and go into a boss fight with the same idea + dodging a few special moves are in for a culture shock. Everyone is the tank, and everyone is the dps. A few can be healers, too.
this about describes the problem. This and another pet hate of mine people not reviving, people are too used to being able to pick dps in an mmo and do nothing in a instance than just stand there and press a rotation ignoring everything else going on around them. If people started to revive not only would it go easier, you spend less on repairs which only accrue on death not downed.
