Brawl - 5 Second Window Intended? Implementation Error?
It seems like whoever programmed this node didn't take into account the time the unstoppable buff is active versus the countdown timer, which ends up giving us only 5 seconds with which to try and land a few hits on the opponent before they are unstoppable again. The node description - "Every 10 seconds both champions become unstoppable..." - seems to indicate the intended design was to give us a 10 second gap in between activations for us to land some hits. This type of gameplay where you wait around landing a hit or two every 10 seconds isn't exactly exciting and really feels like an artificial lengthening of already long fights. There also isn't much opportunity for counter play considering the buff is passive and therefore we can't interact with it.
