Don't! GM just helps gamers solve some problems! The drop rate in Warcraft is designed by the game, that is, the drop rate is fixed when a patch is made. This is the power of Blizzard! To put it bluntly, these things are all luck. No matter how low the drop rate is, there are times when they come out. My friend once came out of the tiger. I haven't seen a CD for more than half a year. I haven't seen it headless five times a day! Never mind the drop-off rate, brush with peace of mind, there will always be!
