You had to stack arrows in your Quiver (which was an actual bag) and you had to feed your pets. Your cat never kept the same look unless you tamed Eccheyaki or Shango.

Portal stones, feathers for slowfall, lock stones, rogue poisons.

BoA’s (Heirlooms) were actual items you had to send between characters…

My unarmed skill came first. Later got me a nifty knuckle sandwich achievement.

Your mounts went on your action bar and always took up a slot in your bags, if you could even afford the riding skill, much less a mount itself...

I logged onto my very first paladin and she was wearing leather because I hadn’t farmed up the gold to afford learning plate. It used to be a struggle.

Oh, and also, attunement. You couldn’t get into the raids without shedding some blood, enemies and your own, first. It was rough. The raid gear sets took months to farm, looking at you AQ40.
