World of Warcraft is holding a pre-patch event for The War Within called Radiant Echoes in which you grind Residual Memories (RM) that can be spent on new gear, mounts, and cosmetics. The only problem is that it takes a lot of grinding to earn this currency, and the events begin every 90 minutes, so if you miss that opening, you have to wait a full hour and a half for the next one.
As broken down by PC Gamer, a single chest piece costs 5,000 RM. All three zones have a weekly quest that nets you 1,500 RM each. So, you can only earn 4,500 RM from these per week. The remaining 500 RM is earned by killing the final boss, bringing you to a total that's enough for just one chest piece.
The normal enemies only give you 1-3 RM, so you'd need to kill around 2,500 of them for the same reward.
It's a minuscule payoff for the amount of dedicated grinding you need to put into the event, especially considering that you can easily miss the beginning of each 90-minute slot. So, understandably, the community isn't taking it too well, calling the entire thing...
