Tier 2 content bugged

As i went to leveling my alts, i noticed that the tier 2 content is not as it used to be.
Frost helgaia took a 1350+ player about 15+ minutes to take it down, 2 people party…
the Yorn Abyssal, the first one, the wipe mech of the last boss is messed up, since no spheres in the room and still got wiped, and a boss of 860 being hit by a player of 1355+ and another of 1090 still takes the regular time to die
is everything ok with this content or is something missing??
