I have a lot of alts. But they're bad alts. They're somewhere between neglected and mediocre. The best geared is my priest, but she's nowhere near the level of my paladin, and I'm terribly inexperienced as a healer. Perhaps my DK is next, but he's not going to be impressing anyone anytime soon, especially since I switched to blood for tanking and have no rhythm to it at all.
Shintar's alt killed Arthas. Before her main. The idea astounded me. I can barely comprehend it when people have alts that can do the tier behind current. To have an alt at the current tier is mind-blowing. How do these people have good alts?
I wonder if its based on how much a person is connected to a character. I used to be Klepsacovic the Troll Shaman and that was me. It took literally months to stop being him and start being a paladin. It almost didn't happen, but we were short a tank that night. Still, they both did achievements and heroics and gathered badges, until one day my shaman just wasn't anymore. I became a paladin. My shaman hasn't even hit 80 and might never. Elemental feels weird, enhancement feels dumb, and you can't heal a mob to death. He may be in Orgrimmar forever, the enchanter with a Finkle's Lava Dredger, a fire hat, and absolutely no raid enchants.
My main isn't just my main. It's more like the leader. My alts are servants, sources of income or some desired item. They have professions to serve my main. To spend much gold on them is pointless. They exist to make gold. At best they are temporary distraction from burnout. They are not real characters, deserving of any investment beyond that which gives them profitable professions. It is the nightmare-made-virtual of everyone who fears economic tyranny: total control, not a single gem or gold piece allowed to slip out of the grasp of the main, not a single free idea or action. All are subservient to the Account, except for the leader, the Main.
She is a tyrant, my main, and paranoid beyond all belief. She knows that it was a stray raid which put her in power and will not let the same happen in turn. Besides weeklies and VoA, no other characters have seen a raid. They have no titles beside the Patient. Except that warlock... she is dangerous, with an old PvP title; only being on the wrong server, wrong faction, and having DPS queue times keep her in check.
The neglected alt is easiest to neglect while the spoiled rich main is easy to keep as a main.
