the thing I have learned the most about pro hearthstone players in the last few days is that nobody knows how to pronounce menagerie
Basic pronuncation is a thing I can let slip for the non-English natives out there. Kripp, all the EU players etc. Most of them pronounce stuff wrong and it is close or they are trying, or its an accent thing. They didn't grow up using the language so in theory it should be harder for them, they pronounce it wrong, ok fine.
But people that are native speakers that don't get it? The word is mostly regular in spelling and pronunciation. At the minimum if they played D&D or Magic or other card games they should be right at home with these sorts of words. Holy hell, they can say Y'Sharaj and C'thun and weird stuff like Cairne, but not a regular ass word like Menagerie? It blows my mind.
I also once read an article about ESports pros, this was about SC2, but people mentioned Dota players also in the comments, that they have no idea how to set up a computer because either it is always done for them or they only have their own and never set up others. I would think a basic part of playing computer games for a living would involve setting up my computer to play at, but apparently, nope. Some of them apparently are unable to do basic stuff like install Skype, or configure their internet settings.
