It is okay, the men and women who do this daily have mental illnesses that prevent them from focusing on something for classic wow gold too long, they will get distracted by something else  before you need to turn in the pursuit.

 The follow up pursuit"Echoes of War" is still not available. Without this being available beforehand, it will still be a warfare zone/disaster area as everyone floods LHC to  try and pick that up.

On a different note, with the Invasion points ending after a particular # are defeated and servers being 200-300% larger than vanilla, a great deal of people will be miserable  if they cant throw many of the dedicated scourge stones/oils. Unless they change anything, the invasion will be on the first day and it'll be nearly impossible to farm anything.

And on top of doing this, they could discharge the invasion earlier.Wowhead says it's shareable, so that shouldn't be too much of a issue.

The event stops after a certain number of invasions, therefore if that amount is not increased due to everyone and buy gold wow classic eu their mother fiending for these mats, the event will be over  in less than these 3 times.(https://feedsportal.com/world-of-warcraft-how-this-game-is-a-classic/)

After arriving in the attunement quest, the exact same NPC inside of the church in LHC provides the quest"Echoes of War" - this quest HAS to be completed before you are able to  turn in any T3 tokens to get T3 items.
