"Healers Are Not Requried" - Challenge

A couple of days ago me and a group of my friends were laughing about the warrior healing memes. One of them being:

So we checked if we could do an expert dungeon with just a warrior and two DPS. It turns out it was surprisingly easy even with wall to wall pulls, even for a non-warrior main such as myself. Our white mage was so kind as to not interfere. She spent her time taking a walk and admiring the scenery of the dungeon.

I don't think this is anything shockingly new but it was a fun experiment and goes to show that a dedicated healer seems to not be needed in dungeons. We also did the Dead Ends (ilvl synched) without a healer. If any of you know of other fun dungeon challenges, I'd love to hear about them.

Next time try with just straight up four Warriors. They do about as much damage as a DPS, heal themselves, AND are already tanks. What could go wrong?

Okay I give you a challenge. Do Shinryu with minimum item level no echo without a healer :)

people have run expert with 1 tank and 3 dps for years

Aurum Vale synced without a healer.
