Chore mono theme event will kill MMO experience

I have quite negative impression against Writhing Wall or Halloween event.
At a first glace, the event gather multiple style people at one place. And feel like people
are sharing their experience under the same mission.

But. Is this really encourage MMO experience? Well...wrong!
This type of mono theme chore event reduce meaningful meeting chance among players.
Because these type of event too much gather ppl at one place, and force them to do boring chore work.

It reduces chance to share information like "dungeon walkthrough strategy" or building tactics.

And more worse.

Recently, I was doing volunteer mission for older DLC dungeon Lead hunting.
But some of DLC dungeon is quite dangerous or almost impossible difficulty
for unexperienced players by solo for the Lead hunting even in normal.

Newer Lead mission can gather people easily, but no one came to older dangerous DLC
dungeon as volunteer except me. (I've never seen pug players who can do no death killing of first boss
of normal scrivener's hall Well...most of pug group are fake role though. )

Just don't gather ppl at narrow zone and boring narrow purpose.
We can't share knowledge or any of experience each other.
This is so bad. What kind of education can we get in FG1 over and over?
