Arma is legit. I joined his discord with low expectations but Arma scheduled a learning run of Kings Fall for me and 3 other players and he and his friend patiently taught us every encounter and answered all of our questions. He really made it a fun and enjoyable learning experience. If anyone is nervous about learning a new raid, don't be afraid to hop in the discord and @ the sherpa team for help. Schedule a time for a raid and you won't be disappointed.
