Anyone here done the hero duels? You choose your hero from the start, you don't build, but it's just your hero. Usually 2 teams of 1-6 heroes fighting, really cool. One that I played had up to 46 heroes to choose from. Every 10 minutes or so, the person from each team with the most kills duels one on one, all other action stops. Once a team reaches the max kills they win. It's awesome, I suggest to anyone that hasn't tried it to go for it!
