After the new Hearthstone expansion "The Witchwood" Blizzard has introduced several bug fixes . one of the fixes changed the voice line of Lyra the Sunshard.

personally, i don't like the new voice line and most of the Hearthstone community (from what i read on the Hearthstone communities such as reddit,Hearthpwn,Hearthstone official forums) that is aware of the change didn't like it either .

I believe that Blizzard would love to make their users happy and this change would bring great joy to Hearthstone players and fans.
