no u still have no chance of it since they didnt nerf anything significant with which raid coulnt deal before on 530 itlv -_-
pretty usless nerf to usless difficulty wont change anything since u wtill need good players to carry u through it and good players just seemed to abandon flex alltogehter months ago.
if anything this 2.5->3.5 sec change should have made its way to normal encounter -_-
