I grew increasingly deaf over the years since WoW launched, and stopped raiding and most grouping with my guild when it became near total. THEY would have gladly kept me, but I honestly felt that with all the study and visual cue watching in the world, my reactions (I was almost always DPS) were just a second or half-second slower than with Vent. And I did feel responsible for a couple of wipes due to early deaths and a significant resulting loss in DPS for the raid. I think a guild needs to be very understanding and flexible to handle deaf players. I have stayed in my guild, still group on occasion with close guildmates who know my playstyle and can adapt to it, but mostly do solo or BG stuff now. I keep looking for an actual "deaf guild," but have not found one. I would join if there were one, since we would all be on the same page and Vent would not be an issue. My point: I really sympathize both with deaf players and with guilds with normal hearing folks in the great majority. It is not easy.
