I have a pair of stories, both from my current leveling of WHM.
The first is more of an amusing anecdote. Roulette put me in Akh Afah Amphitheatre(Hard), and I was waiting for the people that had to view the cutscene to finish. However, I talked with the party about how much I like Shiva, and that triggered half the party to also sing Shiva/Iceheart's praises. The other half of the party jokingly chastised us for being Shiva simps. XD
Roulette next put me at "Keeper of the Lake", and the start of the run was smooth... until we ran into the Einhander boss. Keeping track of what bomb canisters were where ended up being our undoing for a couple of wipes. Thankfully, one of the DPS being a Summoner was a help when a explosion took me out, because they could bring me back. The Gunship wasn't as much of an issue, which left Migardsormar. The Tank did warn everyone of which Adds to take out when, so we didn't wipe. But it certainly came close, and I came low on MP a few times because of needing to resurrect a few times.
