From what I understand it was extremely uncommon back in Vanilla to have more than one max-level character, what with how long it took both to level and to get things done in max-level dungeons and raids.
This is another area in which Classic is very different - while you still get people who just don't like levelling much or simply prefer concentrating all their efforts into a single character to make that one the best it can be, I think it's far more common for players to have more than one character at the level cap after one and a half years of Classic than it ever was back in the day.
While I've been playing since launch as well and have been levelling characters at what I feel is a decent clip for a casual player, the fact that I started on Horde side and then switched to Alliance on a different server has made me feel somewhat behind compared to my guildies. I have to admit I'm rather in awe of the alt stables that some of them have.
Especially when it comes to professions, having multiple max-level characters is a significant boon in Classic, as characters will need the services of most professions at some point, and many professions rely on materials provided by other professions, so having all of that unified under your own roof so to speak allows for an impressive degree of independence. There are limitations of course: For example an enchanter can only enchant their own gear and that of other players; there is no way to transfer an enchant to an alt character. On the whole though, there are a lot of synergies.
This really hit me when I got into raiding properly and started to require a steady supply of certain consumables, mostly potions and crafted arrows. For the arrows, you need a close-to-max-level engineer with a rare-ish schematic or you'll have to buy them on the auction house every time. Fortunately the hunter class leader's rogue alt is an engineer and he offered me early on that I could just mail him the materials and he'd craft the ammo for me for free.
Potions and elixirs make for an even bigger expense and highlighted my dependencies even more as it seemed like absolutely everyone had at least a herbalism alt. Grousing about the prices of potions on the auction house would pretty much inevitably get me the reply that I should just gather my own herbs and send them to a friendly alchemist - as if everyone automatically has that option!
If I sound a bit envious that's because I am, but at the same time the goal of strengthening my own alt stable has become a major motivator for me, even more so with an eye on TBC. Having my paladin at max level has allowed me to do my own mining at least, netting me ore, stone and the occasional Arcane Crystal without having to buy it from the auction house. And part of why I've been so enthusiastic about getting my druid levelled up has been the fact that she's a herbalist and alchemist. She's level 47 now but already has both of her primary professions maxed out. I just need to get her a few more levels before she's able to visit zones where she can pick her own Dreamfoil and I'll be close to having gained independence of the auction house for my potions as well.My mage who is a tailor and enchanter isn't too far behind at level 44, and while enchanting is a major pain to level she hasn't been doing too badly on that front either. I like the idea of being able to craft my own bags come TBC, and if I want to create my own enchanting materials she'll need to be levelled up too. In Classic you can disenchant gear of any level with an enchanting skill of 1, but in TBC they introduced skill requirements for disenchanting different levels of gear as well, so once again, that's going to come in handy.
I guess if you really dislike professions all of this could be seen as a lot of annoying busywork, but I really like the way this slow and steady investment of time and money really pays off after a while. There are still reasons to go to other players for certain rare or specialist recipes, but being able to cover a lot of ground via DIY is nonetheless extremely valuable.
