I had stopped running in GW2 Dungeons because I felt that the drop rate and rewards system was to low for the time sync Dungeons had become. I was use to time sync with rewards to match the time spent, the GW2 Dungeons were so poor thus I stopped.
Just this month I decided to try again and was pleasantly surprised and felt encouraged to try again…until I read about the newest change and the removal of the “res-rush” (as you call it.)
In other games we at least had the option to drag a character or rez them during a fight with relative safety and rush back in to help our team. After all accidents do happen no matter how good the team is. GW2 does not allow even this small feature. For Shame.
You can now once again count me out of any Dungeons on GW2, just no longer worth it.
