I need to watch the whole VOD, but early on Day9 stated he didn't understand build priority and chat was not helpful at all. I think it's a widely misunderstood concept.
If it's not clarified in the rest of the VOD, I was thinking of writing an email to explain the mechanic and mention something like "I play ZK but I assume it works the same in BAR... it goes like...".
But before I do, it works the same in BAR right? I assume it's driven by the engine.
Also, is there no medium prio in BAR? Or is it just hidden by default and can be shown with settings?
