As a spectator, it'll be nice to watch the best players play meaningful games on stream, instead of shitting around with tier 4 decks to amuse their audience since results don't matter right now.
As a player, it'll be nice to test my skill in a highly competitive environment, as I'm never going to be challenging for top 100 legend or in a tournament that matters.
As a Hearthstone fan, it's nice to see Blizzard putting something in the game to facilitate those things, but disappointing to see the reaction from the community. I fucking hate 99% of Brawls but I understand that Brawls aren't made for me. They make one Brawl I'm actually interested in and the fucking community has to ruin it for me.
