Try SWTOR. The original 8 story arcs are pretty fucking rad, and the crafting and companion system is pretty unique. And black people exist!

I was honestly sold on it when I saw the very first raid ever, where the final boss had a completely vertical boss arena. Mitigating fall damage and sneaking in quick group heals as you race to catch up to him before he blows you up is something I'd never seen before, and haven't seen since, in MMO design. The previous two bosses were:

1. A two part puzzle, where you need to split your team in half and solve both parts simultaneously. On Hard difficulty, each member of the two teams needs to cycle through inputting commands into the puzzle box, so you can't just have one person solve it.
2. A room of Sith Warlords that fixate the closest person, and lock them into a one-on-one duel. Everybody—including the healers and tanks—has to fight their opponent alone.
