Realising that the person I invited into my plus groups was the one I boosted to get ksm 
“Guys, why am I still in combat?”
There’s only two times I can remember actually being scared by WoW. One was the quest to rappel down from Valley of the Four Winds to a cave in Krasarang Wilds. I mean, the rappelling wasn’t scary but Blizz totally got me with the Cave Horror jump scare in the cave.
The other time might not count since it was in the original BC beta, not the live game. Started questing in Hellfire Peninsula, just having fun, and then FEL REAVER NOISE. Looked up and it was almost on top of me. I got away, but it scared me enough that I learned the path of both Reavers and always kept my head on a swivel in that zone. To this day, even with all the alts I’ve leveled, I’ve never been killed by the Fel Reaver.
My scariest moment was when I was hugged by a Human Male Paladin. 
Sadly. But I do have a Halloween All Year calendar on my wall. Every month is a Halloween picture and every day has the days left until Halloween.
Scariest mount in WoW? Invincible, it’s so scary that you do a 360 and run away if you see it (which you can’t because it’s invisible obviously).
My first MC run in Vanilla my druid was given the BoE bracers and I was told I needed to equip them right away. I was lagging like it was 2005 and at first when I clicked on them to equip the lag made it think I was trying to trash them. I said no, but then they vanished out of my bag. I was trying to explain to the raid that I wasn’t trying to scam them out of T1 bracers. It took like 2 minutes for them to show up again in my bag.

Speak for yourself.
When i saw human male sleeping with two tauren.
The quest in Draenor where you run up tot he quest giver and she gets SPLATTERED by an Iron Star.
I don’t know why, but the first time that happened I literally jumped in my chair and my knees smashed the keyboard tray. It scared the piss out of me. Not because it was scary but just because it was so unexpected and I was super zoned out.
When I first started playing after many years of Everquest where when you die you lose experience.
My “buddies” who had me thinking of playing had me follow them killing and looting everything as we go. We made our way to the murloc camp. Can’t remember where exactly. All I know is that we all logged for a break. Not knowing any better and being told “Oh you’ll be fine just camping right there.” So I camp out. Hours later I thought it’d be fun and see what I could kill…
First thing I hear…Mrrgrrill! 5 and 6 deaths later swearing that I lost a level.
All the while I hear laughing and Welcome to Wow.
Murlocs. Are always kos to me now.

Seeing Stitches walking down the road outside Darkshire. (During vanilla)
It was the first time I saw an abomination in WoW (the W3 variants were creepy enough) so it was pretty disturbing seeing that thing shambling along, and then seeing that he was like 30-something (I think) in a level 20-25 zone and an elite.
Back then you needed a whole group to kill him. Also I think he could literally kill all the NPCs in town so he was serious business.
The first time I went to Moonguard Goldshire with TRP3 installed. The most cursed content you’ll ever see with your eyes.
… … … … …I think you won first prize for this thread.
When I afked outside of SSC in bear form, and came back 10 mins later to see that an entire group of at least 10 people had performed ERP on me for my entire text backlog.
It was… very descriptive.
Seeing naked Kultiran in front of Stormwind AH.
Or maybe that’s the winner… WTF??
Maybe not scary, but just really eerie and kind of pretty, but eerie. Go to Vashj’ir with the Inky Darkness potion. That zone becomes 100% more unwelcoming to your presence.
The bioluminescence is so cool in that effect, but you’re also surrounded by a void of darkness deep underwater and it’s creepy. Especially crossing the rifts between the zones and you look down to see an even more absolute bottomless black below you. Just enhances the horror of everything.
If you ever want to intensify your Vashj’ir questing experience you should try it!
“At the bottom of the ocean even light must die.” 
Once in a questing party in the BC era, Myself and a bunch of other lowbies were doing stuff in the Swamp of Sorrows. It was our first time out there and didn’t have a real idea of the layout. We’d just made our way to the coast once where the camera spun back to face the beach. The entire zone had that eerie yellow-green cast to it.
I’d become separated from the others somehow; probably to get a quest item, but I don’t even remember anymore. I do remember that it was my first encounter with an orc hunter on a black and red war raptor that was ??? level.
What followed was something Blizz tried to emulate twice in their quests. The WoD intro when you’re being chased through a jungle by a huge army. The more recent thing in Revendreth where the story reveals that spirits were hunted through the woods to make it easier to get their anima.
Neither of them came close to the level of panic this guy inspired, like the Nemises of the RE series, because time and again I’d think I was in the clear, and lo and behold I was Not. I realized a long time after that it was because hunters could track humanoid, and also my stealth wasn’t as effective against higher level people. I eventually kind of numbly began to accept that I couldn’t really hide, though of course I always tried.
I’d become marked for pvp by straying too close to the orc camp in the south of the zone, which didn’t help, to say the least. At first all I could really think of was getting back to my group and that it would be safer there, so naturally I kept trying to trend that way…
Until I realized that I couldn’t do that. In my head I began to think that if he came upon the others that he’d just mess with them as well. So there came a time with all this going on that I had to make the decision to run the other direction into a zone I knew absolutely nothing about, with this maniac on the loose.
When my tag finally ran out and he realized he couldn’t get me to flag myself again (he did the mountspecial thing where the raptor roared at me). He finally left, but I didn’t trust it. I stealthed back to the group always expecting that tool to show back up.
But you know what? I will say this. It was the most exciting zone intro I ever got. When I was doing the Revendreth quests and they were demonstrating how they hunt the spirits I was like 'Pfft. Amateurs."
