That was indeed an april fool's joke. Their racial was "Detonate", when you would, well, explode, dealing shitty damage and burning like 20 mana, and die... PERMANENTLY. You would have to roll another character ^^ Pretty obvious joke.
Btw thanks for sharing all this, I started the game with the Open beta, it was so... different from other MMOs that I bought the game right at the release!
Oh and a little one... Wow was released in EU on February 11 2005, four months after US
So even tough I've played the game since the beginning in EU, there are some things mentioned by the OP that I didn't experienced, probably due to being fixed in those four months. Still there were a lot of funny things indeed... Well funny retroactively because those were just TEDIOUS at the time, but nostalgia has quite an impact on the mind
GOD THOSE WARLOCKS WITH 30 SECONDS FEAR
GOD THOSE SHAMANS ONE-SHOTTING ME WITH ONE WINDFURY (enh shamans were pretty rare in fact, but as a mage I avoided them like the PLAGUE in BGs indeed... Well when BGs were implemented at least, the first was Alterac (40vs40 at the time) and guess how long the queue was on a highly populated server... TWO HOURS. YEAH REALLY.)
And there were 1h+ queue to actually ENTER a server in the EU (wouldn't know about US), and for like two months, until new servers were added. Good thing the game was and still is that awesome otherwise it would have been a flop with those queue times!
GOD THOSE awesome crits with patch 2.0 as a mage, with the new talent trees xD Two arcane/fire mage could easily kill one big geared warrior tank holding the flag with two healer at his side, in mere seconds!
GOD THOSE ENDLESS GRINDS TO LEVEL A FACTION TO EXALTED FOR ONLY ONE ITEM! Augghhhh.
Oh and another one... Frost/arcane was the relay only raiding spec when you only raided MC (and back then you had to have 40 persons almost fully geared with MC loot to begin BWL, which was AWFULLY SLOW with 2-3 loots per boss), because a LOT of mobs were simply IMMUNE to fire... And some even to poison and bleeding like the rock elementals. And you HAD to spec 5 pts into imp. arcane explosion to make it instant and be able to AOE efficiently
Good TEDIOUS times indeed
Nostalgia is great, but if you don't realize that the game is 10 times better now, well you're just a guy blinded by that very nostalgia.
