Hearthpwn

Every day he always crashes the game when starting a game or gets stuck looking for a game

You mean the WiFi bug 

yeah i get this too, it makes it almost impossible to reconnect too, would love to know the fix, have you tried deleting your cache by any chance?

I swear this is one of the Top 3 most annoying things in HS, so I finally learned this is from Wifi only ? Interesting, since that concerns me, and nope once this comes up (it's often for me) you are done and your opponent gets a default win basically. You'd always need to restart, but once you come back "You lost" pops up or sometimes (rarely) "You won" LUL small Indie Company.

Another observation, this always seems to happen in conjunction when Chrome Browser is running simultaneously, I believe it never happens when your Browser is off. 

Then it's not HS related but Chrome related. Use another browser, i never get this issue. Also, chrome sucks for performance and data privacy.

Lastly, HS is related to something else though - when starting battlenet and before the game finishes loading, twitch.tv streams seem to buffer for a bit.

I guess HS uses some form of flash player or something... and it doesn't allow multiple instances. Welcome to 2001 blizzard! LUL
