Wings of Angel was definitely the way to go. I lost some DPS but being able to just rush thru trash that gives no progress or skipping annoying elites, made me jump to GR66 fairly easy. RG is a problem for me since I'm playing non season and the lack of Bane of the Stricken increases the RG fight by a LOT. My gems are below 60 and I'm not even paragon 900 but i think I'm doing ok. Paragon 1100+ and 70+ gems and I should be able to do GR70+.
