As of current we have multiple timewalking expansions. We have so many timewalking events now that they outnumber the other events. IMO I think if they make it so there is always two bonus week events happening the game can only be more active. There would also be less waiting for whatever event you wanted be it BG week or legion mythic+ week. Anyone else agree?
Timewalking:
- Burning Crusade
- Wrath
- Cata
- MoP
- WoD
- Legion
General Bonus Events:
- Mythic Dungeons
- Battlegrounds
- Skirmishes
- World Quests
- Pet Battles
