-Heroes are sent back in time in certain important lore events (the battle of Blackrock mountain, Wrath Gate, War of the ancients, the Gates of Ahn Qiraj .....)
-An alternative for daily quests
-Heroes can perform their task with any chosen specialization (healing, tanking, dps)
-Title achievement, mount as rewards for dragon flight reputation.
-Visit places like they were prior to the Cataclysm or the Sundering.
-No alternate past, no manipulation in timeline, just recording of events, or gathering stuff.
-Timewalking dungeons could be included.
this is a suggestion, it could give players the chance to witness big Lore moments, could also vary the means of gearing or spending time doing stuff at maximum level.
I am a big fan of Warcraft Lore.
