They literally said its the old trials bumped to 80 with minor adjustments to accomodate for the power jobs have at lvl 80. Those minor adjustments probably mean mechanics happening at slightly different paces. If people didnt sugar coat everything SE does maybe we would have nice things by now instead of the same patch cycle for years.
So in short. Yes, I ve played them. Back in ARR and cleared them all even when the servers were trash. Their mechanics are very simple and do not hold to todays mechanics. This was not worth sacrificing a new ex trial over.
