I agree with you on the elevator part.... that was annoying, I actually had a few party members get off at the wrong stops and had to jump down to catch up... some died..
Infact my first time there I couldn't actually tell apart what was a "static floor" and what was an "elevelator" until it started moving..... haha.
I've died on that thing like 4 times because for some reason I stop paying attention at that point and run right over the edge.
Also don't jump while riding the first elevator down..that will also kill you as I learned.
ETA: But in general I enjoy the flashpoint. Boss fights are decent. I got a few pieces of equipment that were better than what I was using so I can't complain.
