Anybody played this mode yet? I just finished my first one. Boy, what a terrible mode. There's some serious pay-to-win stuff going on there. I'm disappointed in Valve for this one. Me and a friend got matched up against a 5 man who all had point pools over double ours. Their year beast wrecked their way through 2+ towers every time it spawned. Ours died nearly immediately every time.
I'm curious to see what other duders' experiences with the Brawl are.
So what is pay-to-win about it? http://blog.dota2.com/2015/02/the-year-beast-brawl-event/ From their blog I don't see anything you can buy to help the creature like you seem to be suggesting. They likely all had lost previous brawls and had bonus ability points as a result, something that you will have as well now.
Win a Brawl, and you’ll earn item sets and other New Bloom prizes. Lose, and you’ll receive a handful of Ability Points to use in the next Brawl.
