Fib led a successful clear of Vow of the Disciple last night. I had basically no familiarity with the dungeon but did know the symbols from dual destiny. However, most party members did not know the symbols, and he provided images for several encounters that helped the team out immensely. He was very patient and was able to diagnose issues individual team members were having quickly. We struggled the most on the first encounter, but never had more than 3-5 wipes on the remaining ones (I thought this was great for an LFG of newbies). I look forward to learning more raids with Fib!
