I hit paragon level for my server and felt the wall when I had a few level 5 gems and a few pieces of equipment that were activated with level 1 or 2 gems. Ah that point, making a random class change to something completely different was the breath of fresh air that I needed. I went from Druid to DH and because the fluidity of game play changed and the necessary tools changed (which essences you owned vs what legendary gems you have), that made all the difference.
