I have an irrational aversion to using my hearthstone in Warcraft.
See, I remember — vividly — when the cooldown was a whole hour, and there was a decent chance of getting stuck behind a tree in some night elf zone where literally the only way out was to hearth.
So, if you’d just used your hearthstone, and you got stuck behind a tree, that was it. Nothing to do but wait an hour. Literally no other solution.
So if you -wasted- a hearthstone cooldown when you could’ve just run a little ways? Sheer foolishness. Gotta save that cooldown.
Correspondingly, the Dalaran hearthstone—which always had a much shorter cooldown and takes you to a city with an easy portal to Stormwind—is one of my absolute favorite objects in the game.
The first thing I do with any new character is open up Dalaran to get that hearthstone.
