I think the best part of this style of event is that, as you said, the leaderboard rewards skill rather than who can play the most. This obviously comes with some exceptions as you need a myth set and a 5x damage elixir, the prices of which have both dropped significantly so I love the new event. Regardless, this one run score system makes it incredibly intense and competitive for those top spots which is awesome. I wish the ESB hadn't torpedoed endgame pvp but hopefully can be addressed later.
