Dying in any game sucks. Dying in a game that means you can’t go back out and farm and gain xp for roughly a minute? Tough.
Heroes of the Storm is adjusting its in-game death timers to a dramatic amount early game, whereas level 10+ is the same as the live death timer that you’re currently playing on.
These changes are supposed to “help set up teams and players to make important strides in the games, while also increasing the importance of not dying in the early game.” It’s hard not to die as it is, but witrh these increased death times, you’re going to want to be incredibly careful, moreso than before. The last thing you want to do is get constantly outleveled by enemies and lose the game because you were dead for far too long.
