Man... I have like... no real pet peeves with WoW specifically. Hm. I mean really it just bugs me when people are shitty to other people, but that extends beyond WoW and is more nuanced than what is expressed in a single phrase.
As for names, idk if it's because I play (often, although not always anymore) on PvP servers (where player/pet names tend to be especially... volatile) or what but I see cringey names and usually just laugh now. Not that my reaction is the most appropriate (I doubt there is a "most appropriate" reaction). I actually had a separate folder of screenshots of stupid names/and or exchanges (almost exclusively from meme-spammed pvp servers) that I would look back on fondly (though it is lost to the abyss now rip numb name screenshot folder). I also don't typically display names anymore (just health bars).
On the note of names though, I actually think "Lunchbox" is a cute name. Like, it makes me think of
http://www.wowhead.com/item=130151/the- ... r-lunchbox which isn't really that interesting of a toy but is also something I thought was hella cute in theory (it's really too bad it doesn't have a cute animation or something). Now that it's been brought up I'm actually tempted to get a Devilsaur and name it "Lunchbox" (and
not out of spite, I promise). And on the note of not naming pets - it can take me some time to come up with a name I am satisfied with, and the last time I had growl on in an instance was when I was new to the game, and at that point I did in fact have a name for my pet

.
The naming pets after what they are in the wild issue I actually kinda feel you guys on. I mean, it doesn't bug me nor make me think less of anyone or even think people are being shitty or anything, but more so I've lamented the dichotomy of it (perhaps 'dichotomy' isn't the best word but alas) kinda as Wain has expressed it. It would honestly be cool if we could name our pets so we see one name and the rest of the player base sees the rest, although that's not a feature I am personally pining for.
