After one week of great gaming experience, Timewalking seems to be dead now. 15+ minutes queues. 3rd Stratholme in a row, that seems to be hard for some players. RNG? What RNG? 2nd party in a row, where healer decides to stay with DPS, who decide to go wrong way, so rest of party wipes.
I guess, that's because Timewalking weekly isn't reset, so players don't have incentive to do Timewalking. Here is where Blizzard start to realize, that while account-wide reps work, account-wide weekly CDs don't, cuz if player is unable to beat weekly CD via playing alts - then he simply has nothing to do.
