Played a couple of matches already and I haven’t noticed. I don’t think it’s that big of a deal. The announcers need to relay information about events in the game, but you’re focused on other stuff happening and don’t really have time to think about their voices.
I’m sorry to hear about your pain. There is already loads of good advice in here and I don’t want to just regurgitate. I have found this video channel helpful in the past so I’ll leave it here. www.youtube.com/watch?v=9vbIO3TpLXY
