It's bad enough that we're synched for dungeons, don't start imposing that trash on Trials and Raids too. If people put in the effort for getting really powerful gear, they should be allowed to use it, unhindered. Also, considering that if you get a couple new players who may struggle with mechanics, at least they can be carried by the overpowered players so the group gets to finish the content rather than suffer through the rage quitting and waving e-peens, wasting everyone's time.
